Full boost, but no power - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Anderson92s · 07-31-2015, 10:38 PM

2013 BRZ
Jdl turbo twin scroll
Tail wastegates and bov
700cc injectors

So the other night i was doing about 143mph on the way home and let off, the car ran find and i didnt notice anything until i went back to town later that night. The car is now boggy, spudders very slightly under acceleration, runs rich idles at 10:1-11:1, but still builds full boost just not as fast and i cannot figure out whats wrong. Changed the MAP sensor (omni 3 bar) and went over the intercooler piping and vacuum lines everything is fine..what do i check now, what should i suspect? I am new to these cars and need help figuring this one out!

Welcome to the forum, Anderson92s ........

I think your car had a .....stroke ......

I'd suggest you take it to a tuner for a complete check up.

I'm sure others will join in with some useful information .....

I hope it recovers.

Could you explain to me what you mean by that?😁

Anderson92s · 07-31-2015, 11:21 PM

It still has power enough to squeak the tires 1st to 3rd but not near what it had

I've read somewhere on this forum, that the ECU is only calibrated for a particular MAP sensor, so if you change it, you will require a retune.

Check hoses under the intake manifold (there's a thread in the forced induction part of this forum)
