forgive me if this has been posted before

I have the following mods: Pettit ecu,downpipe,intake;
Racing Beat Catback and Greddy SMIC.

I would like a little more horsepower what should I do besides going single....will I need a different ecu.
Car needs to pass smog.

thanks for the help

 

hi-flow cat?

 

Pettit ecu was programmed for dp,intake,smic,catback...that's why I was wondering if I need to do something with the ecu, a/f ??

thanks for your response

 

Don't really need to do anything. Just plug in a hi-flo cat and have some fun...

What's your boost pattern right now?

 

Boost is about 12-7-12, I know the 7 is low...just not sure how to adjust/pills?

 

Pettit has a "unlimited"chip for their ecu's that can handle just about all bolt-on mods, even a streetport and 15 psi of boost. You could run 1-2 psi more although yout transition is low and should be figured out first. A high-flo cat can gain you 10-15 rwhp depending on the cat and also a pulley kit. Even the UO main pulley has been documented at gaining 12 rwhp. You can also send out your secondary turbo to BNR for his to upgrade the compressor wheel to get you another 20-25 rwhp or so. Other than that, not much else you can do other than big money mods (streetport or single)

 

I noticed you had 1300cc secondaries and a Denso fuel pump would those be helpful in my case???

 

fuel may help a little bit, but it's more to 'protect' the engine.... if you aren't familiar with the 3-mod rule, you should read up on it. after doing three 'power-adders', you should get an aftermarket ecu, our some type of fuel management, to help from running lean (detonation), and upgrading the fuel system helps even more.

pulleys, hi-flow cat, suspension, new tires.... there are a lot of things you can do in your situation. some might not add power, but will seem like they do (i.e. suspension and/or new tires, flywheel, etc.)

 

thanks...The Pettit ecu is programmed for the mods I have..which I assume maps for the correct a/f mixture along with allowing higher boost.
