Wow, why is the same kit from paxton gaining alot more HP on almost a stock set up compared to the first few application? I remember the first few cars were hitting barely 600rwhp?
Did paxton upgrade something in the meantime? Fix some bugs maybe? Only Catless and mufflers and 665rwhp, wow!
Tuning !!! Fuel/air ratio...You can get over 750rwhp with the Paxton kit, but they advise against it (cast pistons)...Headers would make a much bigger difference in TQ in this case.
The VEC2 is a great tuning tool for sure. My target on my dyno for a blown application is a nice and flat 12:1 unless the customer wants a richer AF then that
