I experienced something strange on my supra last week. The Greddy exhaust for my Supra TT JDM 1993 Auto BPU+, came with an end of cannister exhaust buffel, which was duly fitted at the time of installation. Tha car was running fine at 17 psi of boost for months till on a high speed run the car spat out the buffel and i couldnt find it. Since then the car has started missfiring and missing at WOT. The Boost is showing in excess of 20 psi. Is this missing caused by fuel starvation in response to increasing boost? someone has recommended Auxillary Injectors like the HKS AIC. Is the AIC hazardous as there have been reports of engine damage.My Sp 57 kit is on the way so i dont care about Blown Turbos. Please help as I have a race coming up this friday against the WRX sti Spec C.
