I have been searching the forum for a few days now to get some info. I have figured out the diffeerence between the Cali and Non-Cali ECU as well as the Limited vs. Unlimited. What I havn't been able to find is which mods can go with this ECU. I think intake and 3" exhaust from turbo back is okay, but what about lets say a FMIC in addition to these mods?

 

You can run all bolt-on's plus a ported engine with the Pettit ECU as long as you are able to keep your boost under control.

 

I have a reprogrammed 1995 Pettit ECU that I got from Cam at Pettit. I have a Pettit cold air intake, a Pettit downpipe, a Racing Beat exhaust, a SMIC and a boost controller. The ECU works flawlessly. Mahjik hit the nail on the head.

 

I was running all bolt ons without cats on 93 at 14 psi non-seq. Most of the time I was running 12 though.

 

Running a Pettit Unlimited....

Greddy Intake Pipes
3" DP
3" Bonez Midpipe
3" Greddy catback
Walbro 255 lph pump

The KEY is controlling boost. I am running a dual manual boost controller setup. I never boost past 14 psi.

 

Sounds like I can do an intake and 3" exhaust from the turbo back, aswell as FMIC as long as I have a boost controller.

 

Almost true. That will work as long as you don't suffer from boost creep.

 

Some FD's are different... It's common to have to port the wastegates with these bolt-ons. When dialing things in, start slow and keep an eye on spikes.

I am fortunate enough to keep things under control. However, I am running the stock mount IC. Just take it slow. The limit is the stock fuel system. If you start making over 300whp, be very cautious..
