Changed header and mid size +18hp+12tq
Swapped my 1 3/4 headers with 2.5 catless mids out for kooks 1 7/8 with 3inch catless mids and on first pull with no tuning changes it picked up almost 20 and 12. Tune was spot on and safe so we left it at that
Made 730/640 before and makes 748.5/652 now
on same local stingy dynocom Dyno. This Dyno generally reads about 5% less than the dynojets in the area. Needless to say I'm thrilled with the results. We layed the graphs together but I forgot that print out. It was identical till 4K then you could see the bigger headers take off.
They also did a custom hard line catch can that looks factory
