No, the ECU has no idea what boost level you're running. The only control is the wastegate actuator (and boost leaks). The acceptable boost range is something around 9 to 6psi (I can't remember right now, it's in the TSRM though if you wish to look it up)... it's not uncommon for the wastegate actuator's spring to weaken over time causing a drop in boost pressure.

I have added 3.5mm of washers under the waste gate bracket to shim it up.

boost problem
ok so leme start i replaces plugs and wires. replaced intake tube. checked for leaks cant seem to find any. my problem is if i slowly give full throttle i boost great but if im on it hard it boosts half way up the rpms then feels like it starts to miss. at idle i smell fuel and it spudders every 3 seconds not a misfire spudder but like a blank spot hard to explain more like grrrrrrrrrrPgrrrrrrrrPgrrrrrrr if thats understandable. also if im quick shifting under full throttle it falls as soon as i shift gears and hit throttle again there is a noticable miss but instantly comes back. only throws check engine light if im on it hard. any ideas??????

if the check engine light is coming on at all you need to check for codes. critical codes may only cause it to light up momentarily... many codes don't trigger the light at all.

What can you boost safely on a stock setup?
