Well, the 'problem' is since I installed my MBC.
The turbo just spools daaamn fast.

At less than half throttle I hit 5 psi at close to 3000rpm. Even 1/3 of throttle is enuff to get me into boost.

Now, the thing is that when accelerating I *always* hit some boost due to turbo spooling way fast - but with so low throttle and some boost, my O2 is jumpin' up'n'down which means it's in closed loop.

This is also mostly in under 4000-4500rpm.

So, how bad is it to be in boost at part throttle and in closed loop?

I use FMU.... but ones using AFC should have even more 'problems' with this due to AFC cutting down MAP signal.

Other than this 'problem' it runs real smooth.. xcept that it hits boost soo damn fast
