I just installed my t-trim a few days ago and was wondering if anyone else is running a 2.95 blower pulley and a stock crank pulley that comes in the kit. I am only seeing about 9-10 psi at 6000 rpm on my 306. It has stock Victor Jr. heads a ported Systemax II and a 70 mm t-body. I was expecting at least 12 -14. Is 9-10 normal for this pulley combo or do i have another problem like belt tension or something? The belt seems very tight though. Please let me know your boost levels with these pulleys.
