This why the MPG fooler was built was the problem of the IAT temps diving off too deep on the cold side the ECM cranks up the timing advancement even harder making the engine knock. So this is why I'm asking about the IAT temps. Because just by flipping a switch between MPG mode to OFF you can here the VP44 advance heavy and start knocking when turned to OFF. Then turn the MPG fooler back on then the knock nearly disappears. So back to checking the IAT temp and where you stand in the morning. ECT and IAT temperatures should match exactly. Like here is a screen shot of my OBDLink LX on a first key on.

Just to muddy the water back up again... Most all high-performance pumps are typically built from a SO pump. So most folk typically migrate to the SO even from the HO pumps.

Yeah, maybe an HX35 hybrid. You are no bigger fuel wise than I am. I'm still running my HX35W and zero issues. The boost limits out right at 35-37 PSI. We both have +50 HP injectors and both running an Edge Comp. The only difference is you've got 4" exhaust to my 3" exhaust but I have no EGT's issues.

Like my truck uses a plastic top hold down piece. Then the bolts are just your a typical bolt.

Then there some of us with a 10 year old Air Dog 150 pump with an old school draw straw.

That's what a wastegate is for so you can stomp your right foot to the floor and not be scared of using the power. Wastegate stops the turbo from going to fast or building too much boost. The other thing I would start considering is studs because you borderline for blowing a head gasket.

That all there is to it... VP44 <- Stock Fuel Filter <- FASS Fuel System <- Fuel Tank

I gather coolant? I still need to know the IAT temperature. IAT as it get colder the timing gets more advanced. Typically the advancement get so steep it sounds like a mechanic trying to beat his way out of the engine with a 6 pound sledge.

Hua? Just get a big line kit for the stock to the VP44 and you are done. http://www.vulcanperformance.com/Universal-Big-Line-Filter-to-Injection-Pump-Kit-w-p/ffip59.htm

Wastegated turbo is nice. You know the wastegate is opening up to prevent over-speeding the turbo or getting your drive pressure and boost pressure out of whack.

As for the transfer case you can use ATF+3. I've been doing that since brand new. No issues. If it's limited slip then you are stuck to the synthetic 75w-90. As for open diff I've been running 85w-90 all these years no issues.

I won't worry about getting 1000 CCA batteries. Even in stock standard, 750 CCA is fine. I'm running WalMart 810 CCA batteries and they are working fine for sub-zero weather in Idaho. Batteries aren't the entire trick but good main cables. It doesn't do you lick of good to have 2000 CCA under the hood if the cables can't deliver the full 2000 CCA because of internal corrosion issues in your main cables.

First I would check the IAT temperature with a live data tool. See if the IAT data. At key on the IAT and ECT sensors should match.

Yes. Keep it! Doubling up the filtration doesn't hurt one bit.

I'll bring my truck and toolbox. Yank those twins off, yank those big injectors out and put some smaller ones in. Pull the double stack programmer and TST off. Run just one. It'll drive just fine and very controllable.

So you got a bad ground lead from the APPS to ECM.

Just showing off how to have a nice test port for the OP. Way better than fighting with a sensor on the VP44 line. I'm working on getting these brackets produced for sale. Making gauge install easier and testing easier.

The key on bump is meaningless and just a software thing. Has no impact on lift pump pressure or performance. Just when the key is turned on the ECM boots the software and the lift pump may or may not run. Again depends on the software that is loaded on the ECM.

Already got a test port just add a tee and test gauge...

Normal. I'm also running a ISSPro EV2 gauge and it will NOT drop to ZERO when the key is turned off. It will display the last reading. That is because the power is cut to the gauge and stepper motor does not have a return to zero spring. So it will just display the last reading till key on.

Duct tape corner...

Might of been easier to do the Jeep module over modifying this one.

Sad part is Volkswagon called me to get his account going again... Post this and start working on his truck to have it burn up in a shop fire. Just remember your still part of the family here no matter what you choose for a truck.
