This dyno session was with all engine mods to date. The first and second runs were to gain a baseline. In the third run we removed the HPP+ engine tuning and found more power. More mods and dyno sessions to come.

The new mods in this session were a ported MAF, LT4 Knock Module, Throttle Body by-pass, and Hypertech Adjustable Fuel Pressure Regulator. The whole power band showed improvements but, the curves weren't real smooth. I'm going to try changing the plugs to smooth it out.

300 RWHP!!! The only changes this time were new NGK TR55 spark plugs. I am very happy with these numbers!
