for the few whom like to discredit what I can do and mention. A week ago here is one I upgraded that already had the upgrade. Feed back was all positive

.

Closer to 1000HP where the closed loop cooling can’t keep up.

Details on the 3.5 John? Is this an upgrade from the Whipple level 3 only or can you take a stock PCM and program it to your 3.5 level? Does the PCM have to be “cracked” already?

I can do both stock and already calibrated by whomever. First and foremost all testing plus internal inspection is done beforehand to make sure the platform (ecm / pcm ) is good - and stable working condition and no internal corrosion nor any damage to the board. They all get opened up for that end. Basically my point for doing so --- to make sure all of it is good and solid instead of loading a tune and taking your money calling it good. I do not want to load and calibrating chicken soup when I have chicken chit as the base stock to begin with for a jist. Can not tell you how many times I see this especially with recaled MEFI s and the 555 s after the fact that the freakin ECM is not in good working condition internally and 100 percent corrosion free

What are the power numbers with the 3.5?
