BOOST CUT???

Post by mitchep3typer » Thu Aug 10, 2006 1:47 pm

My set up k20a gt30rbb full race style custom kit ect.... I have been running only 10lbs lately @310whp i Have almost rasp the concept of the whole tuning thing, so i decided to get the gm 3 bar map sensor 2 run more boost. i have now tried 2 diff vaccum spots checked then double checked the wiring, 1st gear fine 7500 let off 2nd gear bam as soon as i hit 6000 rpms it feels like im hitting a brick wall! as soon as i get to around 14-15 psi full throttle i can go past 6000 rpm i have no idea whats wrong i have tried changing the calibration using the motec option and the netronics option for map sensors neither one will work. Please help me.

i did just notice that the the calibration i was using the cold/hot boost cut was set to 10 psi....do u think that may have been the problem.

Could be boost cut, or it could be the lean protection. You will have to look at the datalogs and see what is actually happening.
