I replaced my clutch recently and while everything was apart I decided to gasket match and polish the interior of the parts I could.
-I opened up the TB circumferance a bit and polished the interior of it both the in and the out
-Next was that black plastic piece connecting the TB to the SC intake . I opened up the exit of the black piece with a dremel to more closely match the SC input opening
-After the SC I gasket matched the large "horn" to the SC output opening and I polished inside the connecting horn as far as I could both at the in and the out which leads to the IC
-After the IC I polished inside the smaller "horn" input and output and also gasket matched it to the intake opening
-I gasket matched the exhaust to the exhaust manifold and had the precat gutted
I have 15% and a 2% ,WMW exhaust ,cust cold air and I'm only seeing 14 to 15 lbs of boost and idle vac is 15in cold and drops to 11 warmed up
Did i make a mistake by doing all the work ?
