My97 runs perfect except that i cannot floor the car, i can put pedal flat in 1st & 2nd, but after the it boosts too high in 3, 4 or 5th and cut the fuel off, i am running no mods, i have been told the problem is a t-piece between turbo & intercooler by howard at HDC he says it has a restrictor inside it and it collapses causing this problem, but does any1 now the name of the part so i can get 1 please.
