Hi Guys, fitted my cam, gone from 233/237 to a 244/257 and i have also gone from ported LS2 manifold to a 92 FAST, however i have retained the same Nick W throttle body (90mm). I have got the idle speed at around 950rpm and it sounds sweet, slight lope but nice and even. I want to play with the tune a little and will get her on the rollers this week with any luck. But just to cut expense on time and money i would like to set off in the right direction.
I was thinking that i am going to have to richen it up at the top and also can i be a little more aggressive with the timing as i have more cam duration?
