Hey guys, a buddy and i are going to fabricate a turbo to work with my 4.6L/5speed and the only problem i am running into is getting a chip that will have different timing in the fuel map. I just know the timing changes are practically critical. any help at all guys thanks a lot and all you guys on here are great and have helped me a lot with my truck.

 

Custom tune from someone, a canned tune with just adjustments won't give you the proper results.

 

And, I think you'd better take that "one of a kind" baby to a GOOD tuner who has the right instruments to read what you've done to it.

Beyond that, I suspect any chip will do the job. It's all going to be in the tuning. This is software, not hardware.

A proper tune is very critical on any forced induction engine. You also need to have a larger fuel pump, larger injectors, and a maf with enough range to measure the additional air from the turbocharger. I would recomend running the 05+ slot style maf in blow-through. Blow-through offers many benefits such as reduced heat due to venting the BPV to atmosphere and better throttle response from having the MAF close to the engine. I have maf sensors, flanges, and adapter harnesses on my website to make everything work the right way.
