i found that if you go to high on gain, then you get the boost creeping over your desired psi, i use 16% gain, then set the psi to what you want.

The fact is even i let the gain to 38, now desired psi 10, start boost at 7, 8 or 9 range, the boost doesn't go to 10psi, 6.6 maximum on the electronique device, same thing on boost gauge .

2 manipulations to go to reach the 10 psi:
- raise the gain up to 70%
- false the desired psi to 14 psi for having 10 psi.

What about our exhaust manifold, red color isn't good at such psi right? Seems the start boost for me perhaps to increase the boost by spooling the T2 too much.

thx

is your ignition timing ok, to much retard can increase your exhaust temp, or fueling, then again my top mount did glow red on the dyno.

I'am in 14/15° range at idle motor and oil temp like 90°

By fuel you mean too much fuel? Because i'm still with stock injectors and stock fuel pressure.

Perhaps our stock ECU runs very rich in 5500 revs area.

Thanks guys

hmmmn, so applying the handbrake (and presumeably turning off the ignition) prompts the turbo timer ?
