Re: So How Big
misinformation.
theres nothing wrong with going to a 58mm TB on a built motor. tip in is awesome, truck lunges pretty hard coming off idle. it did require some tweeking in the tune, but nothing major. if your running a big turbo with a big intercooler and 3" piping, the larger TB is just what you need.
an added gain is also a revised TV cable bracket. if your using a built tranny that shifts overly hard at light throttle because of increased line pressure, you will imeditely notice the softer part throttle shifts, that increase in firmness as you increase throttle position. its a great setup in my oppinion.
