Tuning for Boost

[dbh86]

After screwing with some tunes, I feel like the tables GM decided to use to tune this motor are either inadequate or I'm not seeing what I'm looking for.

How do you go about tuning fuel vs boost? Can you?

on an 02 you cant tune boost just more fuel

x2 heat is what will determine boost along with engine rpm . LB7 is a traditional fixed turbo its not adjustable like a VVT is .

Do you have an adjustable wastegate? That will allow for more boost.

No, not tuning to make more boost. Tuning for fuel relative to boost.

I'm pretty much wondering if I can change how much fuel I'm getting at a certain boost level.

B0751 will control the mixture.. Max injected fuel quantity by RPM and MAF flow rate in G/cyl

Ya, but that only sets the upper limits for the amount of fuel.
