    Maybe a stupid question but I’m having trouble finding non-conflicting information. I know the PowerMax is a fuel only box. I am trying to figure out if a box for an 01-02 can work on a 98-00 truck. I know the MAP sensors are different (plug and voltage values). I have read some info saying that unlike EDGE the PowerMax box will work on all years with a MAP adapter harness. Can anyone here confirm or deny this information? I have tried to contact TST but they are closed until Monday.

    Is there a way to tell which Denso diode I need... by looking at the alt is still hooked up? Like maybe that threaded bolt coming out is in different spot?

    Hi All, my truck has recently presented a new issue. The oil pressure reads rather high, mostly all the time on the gauge on the dash. I'm thinking the oil pressure sensor could be failing, but I would rather make sure my oil pressure is correct. The bad news is I'm about 200 miles away from home for the next week and don't have my service manual with me (doh!). The good news is I have access to tools so I may be able to solve this while I'm here. I have a mechanical oil pressure gauge and was thinking about testing the pressure first before making assumptions, does anyone know if anyone posted an article about how to prope…

    I need some help. I've got a 1999 Ram 2500 Cummins 4x4 auto transmission. I checked for ac noise and got a reading of .093 So I ordered a Nations 180 amp alternator and it came in today. My ecm was junk P0606 code auto computer specialists received it yesterday, waiting to hear from them on whether it a yes or no on being repairable. In the mean time I want to remove the tuner that is on the truck and put it back to stock. It has a early model Edge EZ manufacture date was 2008. I followed the wiring coming from the tuner, two connections that I saw were one to the maps on the drivers side towards the rear of the engine the other connection went to Idon't know what i…

  6. All my attempts to explain the 53 casting number from Brazil that affected about 100,000 blocks that are prone to crack under stress of towing seems to have failed. I have been trying to sell my 1999 Cummins but one questions that shuts down the sale is the 53 Casting Number. The original owner towed a bumper pull RV from coast to coast for the first 150K miles, NO CRACKS. I have explained that it's not just the 1999s that cracked but some 12 valves with 53 blocks and 24 valves all the way to 2001. Some blocks that cracked were 54 castings and 55 castings according to what's online. Maybe there has been more castings, who knows? Are all 53s subject to cracking? If that's …

    A quad is on my list of things to buy but I’m not that far down the list yet. My truck needs new injectors sooner than later though. I would like to go with something in the 7x.009 range(100hp) Can I get away with running the bigger injectors before installing a tuner? What might it run like? I imagine they would greatly benefit from the timing adjustment that comes from a tuner but would it still be streetable for the time being?

  8. I own a 1998.5 24V 2500 long bed extra cab, with canopy. Pretty well stock powertrain. I installed a new HX35W turbo a couple of months ago. Currently running a Herko fuel lift pump that gives me18 psi at idle. Maintains 10 psi pulling a decent load up a hill. Today I installed an A-pillar gauge package. So far boost, lift pump pressure, and exhaust temp gauges are functioning. The transmission temp gauge, I'll hook up later. This January we purchased a 23 ft RV trailer. We've been getting it ready for camping season. Empty weight of the trailer is 4,950 lbs. Dual 3500 lb axles under it. I just installed new tires on the trailer and upsized them to a higher w…

  9. Would this mod be worth it... Thinking about installing a manual override switch for the fan. My temp gauge goes to about 210 on hard upgrades pulling my trailer (normal I understand) and wondering if it would make any sense to start the fan earlier (somehow) if so how would I hook that up.

  10. First time posting but I’ve reading and gaining from this site for quite some time . Thus the title of this post. I’m really struggling with my truck and I’ve read just as much as I possibly can. My background (just so no one is afraid to through anything complicated at me) is 10 years of diagnosing and repairing medium and heavy duty trucks and now about to reach my 5th year of being a shop manager. Sorry this might be long winded. My 99 is a fairly new purchase and it wasn’t acting up when I got but now it’s getting terrible. The two main issues are : when I first leave my house and start driving it will (only once or twice) loose power but it’s …

  11. Started by skyhigh4by,

    Can a failed or failing MAP sensor cause my truck to be very sluggish down low and continuously the P0234 code? I once upon a time had an edge ez but it’s gone now. The boost elbow that came with it is still installed though. I have a fass lift pump and a FP gauge. Otherwise all stock. Truck feels like a total pig off the line and doesn’t feel like it starts making any power until 1800 rpm or so. Also has trouble holding highway speed in OD on any hills even empty.

    How long do you have to keep the batteries disconnected to drain the computer, in order to reboot? I need it to be rebooted so that it will shift out of 1st gear (automatic trans) without removing the relay & manually shifting only giving me 2nd, & 3rd gears.

    I have noticed a big increase in the amount of smoke/vapor from my vent tube, seems to happen since the weather turned hot. Day time or night I can see the vapor coming out around the truck. Runs fine no loss of mpg. Doesn't smoke anymore out of the oil filler hole. Doesn't use any oil and I only have a drip or two fall into the driveway. A/c controls, 4x4, and cruise all work as normal. I did the moparman mod this winter so it's my first year with it. Is this normal? Or should I be looking into something?

    Hello. I used the search option here to find out about my P0606 code. It sounds like my ecm has given up the ghost from what I have read. But I will let all the things that it is doing and hopefully y'all can confirm that it is time for a new ecm. I did a ac noise check. I'm getting .092 volts for a ac noise check. When I start the truck it will not rev higher than 1400 rpm, it goes from idle and jumps to 1400 rpm that is the only rpm range it 850 or 1400 that's it. I replaced the apps and it made no difference. Also the wait to start light will come on sometimes and sometimes not at all and other times there will be a delay in it coming on. I put my obd LX…

I just recently finished swapping a 24v into my ford and have been having a problem getting it to start. Before I say this my heater grid is not hooked up and i know its horrible on the motor but the truck will only start with a small hit of ether.Once its started it runs perfect. Idles great sounds smooth and revs up like it should.Once you shut it off and try to start it right back up it wont start. It wont even sputter or sound like its trying to start. The vp44 is brand new and was part of the problem originally when i first started trying to…

    Okay I’m not sure I fully understand what putting in a lockup switch will do. I understand how it works and why to put it in but I need to know exactly what changes when it comes to drivability. I guess what what I would like is a 3 way lockup switch that 1. Has completely stock lockup function 2. Can lock/unlock the t/c on demand 3. Can just prevent lockup from happening until commanded by the switch and then can unlock via brake pedal. Is that hat how they all work? Or am I asking for something that doesn’t exist. Ultimately I want to keep it as stock as possible for people like my wife or whoever may use my truck bu…
