Hello just need some expert advise,
I have a 90 toyota supra turbo. Engine is fine no leaks or what so ever.Turbo condition is unknown but does not smoke...and still turns..however when i drive running on 2nd and 3rd it would not go fast like it used too. Even when i floor the gas pedal it seems like i did not press not the gas. the RPM goes up slowly and even when i press on it hard..like u can feel that the pedal is pushed fully..Please help..anyone..
Thank You
Noremac

Now I can bet everone is gonna tell you to search but I just did a search on Boost leak and didnt find much info as to what it actually is...

Its when there is boost(the pressure your turbo makes) escaping from either a vacuum line or an Intercooler pipe. Basically check over your car for lose pipes or lines that have come off or been disconnected.

OR
Maybe even your stock bypass valve may be dead. I raced an accord once with a bad bypass valve and would get beat all the time.

Put in a aftermarket BOV and he could no longer touch me. haha.
