Ways to combat boost creep Options

[6G94celica]

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.

ok i was under the impression that 13 was way more than stock. plus with the fresh turbo and larger compressor wheel 13 should be fine then. i know the smaller the exhaust the more back pressure but does anyone think that a three inch turbo back through that muffler is to free flowing.

Yes, in a way it is...
The stock wg setup on the ct turbo's has a hard time dealing with boost creep on a free flowing exhaust. A few people remedy this by going with a 2.5in downpipe or keeping the stock one, but then you also loose a few hp from the smaller exhaust.

On a cold day, even with the boost controller off, I'll probably hit about 14psi. This really isn't an issue though, as 14-15psi is were your going to want to keep the boost at anyway.

7psi = Crazy slow
10psi = ok but still slow
13psi = Nice
15psi = Ah yes, this is why I did a swap.
