I just purchased a 2000 Z28 with a forged 8.5:1 370 in it. It is still runnign on a 346 H/C/I tune. Does anyone have a Bin file for a low compression N/A 370 they could send me for HPtuners that would get me close? It would be greatly appreciated. I could not find anything in the repository.

 

It would be a good start to change the cylinder volume from 0.70821 to 0.75790 liter.

 

I did that already. It made a huge differnece in the way it runs. It has been along time since I have done a full on tune. I guess I am gonna get off my butt and install the LC1 wide band and use the HPT RTT and get this thing dialed in.
