Starr 90mm TB - Altering tune for larger TB

Post by Whyzee »

I've just purchased an NVRAM so that I can have a go at tuning myself!

Car is a VS with all factory VS s3 roller cam gear. I'm about to fit the Starr manifold with 90mm tb and I'm unsure of which parameters need to be changed in the tune.

Do I adjust throttle gain? Or shift points/line pressures? Or a combination of both?

I just want to get my head around it a little more before I go ahead and fit the manifold.
Cheers

Yes throttle gain and normally AE table. Unsure of shift points as I never tuned an auto.
I'm the director of VSH (Vlad's Spec Holden), because HSV were doing it ass about.
