You're overboosting. What is your WG spring rated for?

Check your setup, on map 1 you should only be boosting to WG spring pressure. Set FF to 0 and try a log on map 2.

Check your driver's side filter, make sure there aren't any cracks. At least the HPFP isn't crashing but those pressures are still low. Could be a leak, bad LPFP sensor, or bad EKP.

Here's a log from map 2, got kicked down to map 1, I think because boost safety set to low? Should I raise it from 18 and try again

Overboost...FF is too high, lower it to 40. Bank to bank trim variation is pretty high.

How can you tell when HPFP is crashing? when it drops below 9?
Are you using any Meth or e85?

Remove your rear O2 sensors. It's Pins 19 and 20 in the small black subconnector on the JB4. Then reset your adaptations and relog. This will help with bank to bank fuel trims.

Default Question - 04-19-2017, 07:51 AM

Is this something that normally needs to be done on all ST cars?

Are you saying this because his AFRs on bank1 and 2 are off?
or
Is this part of the Single Turbo setup.
