Lets start by making sure you know to ignore the stock boost guage and get an after market guage.

The "free boost" mod gets you about 12.5 psi on a 92 TT. Without fuel system modifications setting the boost past about 14.5 on pump gas is asking for trouble. 2psi is not much in the grand scheme of things.

Not knowing your current modifications I'd suggest the following:
1) Gut the precats, Gut the main cat or replace it with a test pipe or hi-flow cat. .
2) Get an open element air intake.
3) replace the stock downpipe.

The three steps above will result in more peformance than the 2 pis you'd be able to run from an EBC.

Once you think your ready for a EBC first get a datalogger. this will allow you to see what the car is really doing and make sure you do not kill the engine.


All that said All of the EBC's see good the apeix avc-r and the greddy sbc-id seem to be the top. Depending on your long term goals you might be better with a device like the maft-T pro that really can allow you to change you air intake system, fuels system and control boost.
