Rusty XR6T Donating Members 516 Member For: 15y 30d Gender: Male Posted 09/03/11 05:06 AM Share Posted 09/03/11 05:06 AM I read an article the other day that stated the FG Turbo range has overboost as part of the normal turbo operation.Apart from a different turbo to the BA/BF it said the FG has overboost covered in the ECU for a little bit of an extra kick.I've read it in quite a few places now and was just looking for a definition on what this meant exactly. I know you can experience overboost when messing with the intake system and the exhaust, and that overboost was a bad thing, but most of the threads have been directed at BA/BF's. I would assume because this is going outside the parameters of the ECU, is it still a problem with the FG's considering this overboost function in the ECU?I'm only talking about completely stock here, so only from factory.Can anyone shed some light on this?

Rusty XR6T Donating Members 516 Member For: 15y 30d Gender: Male Posted 09/03/11 05:14 AM Author Share Posted 09/03/11 05:14 AM So overboost is part of the normal operation of the car, in short bursts of course its like Indy cars allow extra burst for overtaking etc but only a limited amount.Does anyone happen to know the stock boost PSI and what it is allowed to spike to?

I never did. Mine never made 10psi stock about 8-9psi on the dyno boost gauge.
