Gains with HPP3??
Gains with HPP3?? In the advertisement it says that you can expect a 19hp and a 21tq gain with the HPP3 for an LS1. Is this true or false. I don't hear much about HPP3 except for the fact that its good for reprogramming fan temps and tire sizes. See one on E-bay for pretty cheap, just wanna know if I should bid or not.

Re: Gains with HPP3?? The truth.....i bid and got my hpp3 on ebay....and not to bash it but its really only good for fan temps and shift points.....if you want more that that your better off gettin something like LS1 edit or gettin custom tuning..i know i will. My 2 cents
Re: Gains with HPP3?? Everyone would pretty much agree that the HPP3 gives you next to nothing in terms of hp/tq gains, but helps with fans, shift points, rev limiter, shift firmness in A4's. Now Diablo predators have been reported to give up to 17hp when using the power tuning plus user adjusted spark advance and power enrichment settings. do a search, you'll get a lot of good info.
