[QUOTE="blownstang4.6, post: 16127088, member: 129006"] Would what matter? That the afr is lean? No. That you had slightly low psi in the tires. If you aired them to 35psi it might post a few extra hp. Going from a 3.47 to 3.33 is nothing. That's only 1 step down. You added a bigger intercooler so need to force more air through it. As an example I have a V1 S on my Mach 1. Previously it was on my GT. Non intercooled with a 3.6 pulley and powerpipe it made 9psi. I added a Procharger intercooler and dropped to a 3.33. It made the same 9psi. Only gained an extra 5rwhp on the dyno. I then dropped to a 3.125 pulley and it made 12psi. Each blower is going to have its sweet spot. You might just have to go down to a 3.25 or 3.125. On my GT at 6300rpm the setup made 12.15psi. On my Mach at 6400rpm it makes 11.66psi and 12.4psi at 6600rpm. This is on a stock motor auto Mach with low timing. [/QUOTE]
