a long time. hes a good tuner, just very hyped all it is. Its all about numbers and putting them in the right spot. tuning a car is not magic. get your a/f’ where u want them, pull timing till you see it not gaining, then adjust cam gears
I’ll leave it to dennis @ hybrid cause he tuned alot more cars then i did.
Not that i am afraid to do it, i just cant do it on the street and he can do it faster then i can on the dyno
but none really goo as fast as they should at least compared to #'s givin
