tuning a 2011 ctsv with twins, ive done dozens of 4 digit hp sbe ctsv2's but this may be the first one that ive had crack 1000 wheel on a 2 bar OS enhancement.
with up to 9lbs on the gate shes fine pulls clean, makes 18 psi or 230 kpa, and no issues pulling to the limiter at 7400, and make about 1020rwhp
throw any more pressure at the gate to raise boost even just one psi, it hits a weird fuel cut, sooner the boost ramps in the earlier it happens.. when it happens it drops it drops current inector duty cycle by approx 65%.
boost limit fuel cut disabled
all tq limit fuel cuts disabled
fuel cut tq mgt type= none
trans tq mgt type = none
all prediction coefficients zeroed out
maf signal wire pulled or not does not matter
maf sensor state stays "failed"
0 or maxed maf curve makes no difference
cyl airmass registers 3.3 to 3.5
back to back to back test.
please help
