Well, I get boost, just less now then before. The bad news is, I had to trash my track plans today because my TT isn't performing at its peak. The good news is that, now I have at least another week to do some fine tuning and practice my launches. When I got the car last week, it had .9mm torch tips in it. This was good for about 14 psi. I bought the car from a guy in CA where premium gas is only 91 oct. Here its 93. I was told .8mm tips would push about 15 psi. I followed the instructions I found on Zhome.com and switched out the torch tips. Then I was building less boost (12-13). I checked all my connection, and they look tight. I finally decided to forget it and put everything back the way it was. Did that, but I'm still getting only 12 psi. These reading are w/ the stock boost gauge. I know they're not always accurate, but I can also feel the boost difference. What might the problem be? What areas should I be trouble shooting.

 

You may have a boost leak. You probably didn't clamp something tight enough or left something off or something. Check it out.l

 

T-Bolt clamps are best for higher than stock aplications. I'd get sopme you can get 20 of them on ebay for liek 50$
