Hi oldblue,
Welcome to the forum :cheers:
A starting point is reading the "What to Tune Steps" links >here<.
A wideband is required, especially with boost.
Generally, these steps are required:
- correcting the VE table to match engine's air input ability (isolate to run from VE only and apply wideband correction);
- correcting the MAF table to match ditto (isolate to run from MAF only and apply wideband correction);
- correcting idle air/speed (various tables including throttle cracker/follower).
During load, do not allow AFR to go lean and do not over-advance timing.
People with specific supercharger experience will chime in.
What injectors have been installed? Keep the timing under load at 11-12 degrees to be safe at 1st not good for power but if it is lean you have less chance of hurting the motor.
