I dont have any RV experience, but I can say my gooseneck horse trailer pulls and backs WAY better than the old bumper pull we had. I can get the trailer in and out of much tighter places even though it is longer than the bumper pull bt a good bit.

Check the vacuum operated collar on the front passenger axle.

5 is fine. Too little timing won't hurt.

Nope, they work until they don't regardless of injectors

sounds good. I never ran the New tuning on a stock injector truck so I dont have a great grasp on how much fuel you can throw at it . easy enough to find out, just go WOT from a stop, if you pour blakc smoke then adjust your 0psi setting down, if it is too slow and no smoke adjust 0 psi up. Do that until you are happy, then build the rest of the tune off tthat starting point. Keep in mind you want to use your full throttle range, IE you dont want %20 to feel like WOT, you want WOT to feel like WOT. If you have an auto your trans will thank you.

yep canbus fuel. Fueling you really can't hurt anything on stock injectors. you could run %150 of stock from 0 psi to 30 psi and be just fine. I call it the S03 tune lol as for timing it is hard to hurt anything, but all the tunes I created for the site use a safe timing curve. The important thing is that timing retards when you get on the throttle at low rpms. load timing and throttle reduction timing handle that.

I would at least step up to 7 x .010's depending on power goals. A nice set of 7 x .011's would still be easyish to tune and provide ~600 hp worth of fuel for a DD truck I think 7 x .010's are the right choice provided you are happy at ~525-550 hp

With stock Injectors and no wiretap you can start with a tune from here but I am guessing you will have to add fuel to make you happy. Just run it on levels 0-3 if you don't want wiretap.

I believe it is either installed or not,. I don't remember worrying about it when I did mine.

1/4 pipe I think. you can find that on google.

an -08 if I remember correctly

You need the Iquad Bluetooth or Wifi adapter so you can tune the V2, the pod can't tune and the old screens are no longer supported. as for updating, follow these https://mopar1973man.com/topic/12025-how-do-i-manually-install-the-quadzilla-driver-load-the-quadzilla-v2-tune-on-windows-10-8-7/

no, Low popping injectors can only be due to the build of the injector.

@pepsi71ocean try again when it gets cold. my issue was like a light switch at ~16*f ambient on a cold block. you are signficantly warmer at that temp. none of the reported starting issues happened when it was above 20*f

If there is no play then I wouldn't be worried. that's not bad for 200,000 miles

we have full wiring diagrams in the articles section. Go over there and start pinning out the trans wiring / pcm wiring / and ecm wiring. The issue should be in the pcm to trans wiring if I was to guess.

like a turbo. hard to see any issues in a picture. more important is how much movement the compressor has in and out?

Stock 2nd gens are not power houses. Throw some 7 x .010's and a quadzilla adr on it.

I'd be looking at the injectors personally. If there were no codes present

how's fuel pressure to the VP? any leaks in the fuel supply?

very interesting.

how many miles on the injectors?

Use the part number lookup tool to see what parts are the same and what are not https://mopar1973man.com/cummins/articles.html/24-valve-2nd-generation_50/part-number-lookup-tool-2nd-gen-24v/

No electric sensors are not always %100 accurate, they don't need to be. They are used to sense change in boost as a reference point.

you completely removed the edge and plugged the map back into the stock wiring? If so, yes it could be a map stuck reading 0 psi.
