i have an 87 tII with:

dp and hks exhaust
hks filter
fcd
greddy boost controller
stock main cat
mild wastegate port
680cc sec.

i cannot get the boost over 7.1 even with the duty cycle at 100%. should i be worried? at first i thought it was just my waste gate doing its job but when i maxed out the boost conroller i didnt really make a difference.

 

Replaced your stock cat with a Bönez Turboflo Cat from rx7.com.

 

ebc is hooked up wrong or waste gate is stuck/overported.

3rd scenario is you have a boost leak.
