Need help tuning a twin turbo Buick 350 with a wideband and blow through..

[jay3000]

Just got the TT buick put together. Still working out a few issues.. 8 lbs of boost..

What I am looking for is is to copy as best as possibe the AFRs of a relatively stock GN with a Holley carb and stay on the rich side for safety..

What kind of part throttle with boost AFR would you likely see, and also what WOT AFR would you be looking for on your fuel map..

Thanks,
Jay

Part throttle on the Turbo 6...12.2-12.5
Full Throttle on the Turbo 6...11.0-11.2
Safe numbers... Lower the numbers richer the mix HTH
Try the Turbo V8 conversion section

Wouldn't want to post the same question in two different sections. The AFRs should be the same for v8s or v6s.. Same engine.. Just two more cylinders.

Thanks,
Jay

Please come to the B4Black section and look for Warwagon (Adam). He's doing blow through and I'm sure he can help you.
