Ok so before my car died my boost gauge at the most i ever noticed read about .9 bars. calculated thats about 13 psi. i bought an upgraded ct26 with a larger compressor wheel from brashboy on ebay. im not sure what the wastegate is set at but this seems really high. i dont want to wreck anything internal and only want to run about 8 or 9 psi. also i have a custom 3 inch exhaust that i personally built with a high flow xlerator muffler with a single 3" inlet and dual 3" outlets. i know im running some major boost creep and am wondering how best to stop that and add some backpreassure to the turbo to slow freewheel.

QUOTE (DEATH @ Jun 5, 2008 - 1:39 PM)  Depends on where they were sold. US 2nd gen is only 7-8PSI.  No its not. If your only getting 7-8psi, you either have a very restrictive exhaust, or the ecu is keeping you in low boost mode. All stock 2nd gens should hit about 10-11psi stock. -------------------- 15PSI - 30MPG - Megasquirt Tuned

The MR2's I know around here were limited to 7-8PSI until they added an MBC. Admittedly I have almost no experience with alltrac/GT4's but I know that the MR2's I know have this "problem". Please help me out if you can cause I can barely hit 6PSI and I have no codes other than the speed sensor one we discussed caused by my not yet having fixed my speedo/speed sensor/ecu issue.
