K&N short ram intake, injen upper charge pipe, looks to be lowered, headlights are aftermarket or painted black inside and tinted tails from the pictures. What psi is it boosting to, could have a tune, depending on the brand it is always activated (hp tuners) or trifecta tune is activated by either pressing the traction control button twice (putting it into competitive mode) or by pressing the cruise control button on the steering wheel. Stock you should be boosting around 15psi, any aftermarket tune is usually 22-25psi, so asides from the huge increase in power, you can see it on your screen

 

K I get max 180 kpa or about 28 pounds

 

I'm assuming the digital screen is aftermarket as well? I am new to this but very happy with the car what else should I do to it my goal is to get 440+ hp out of it.

 

And thanks a lot for the info I have it booked to get a block heater put in on Friday. I know the blow off valves are changed on it as I've heard stock and mine sounds much nicer, I don't know about the exhaust but it's possible. I did 0-60 in 4.8 seconds. Like I said I love the car never had one like it and the wife finally caved took it for a test drive and fell in love!

 

Digital screen is the RPD. Only came in '09 and '10

180kpa is 26psi. And for a goal of 440 you're gonna have to do a turbo swap period. Your bpv, not a bov, is probably the stock one but since you have a k&n sri intake it makes everything louder and crisp.

What kind of turbo swap do you recommend?

Welcome to the site,
keep us in mind for any of your GM parts needs.

 

Nice car congrats. Go for ZFR, wr3, bnr, s20g. Don't forget a clutch as well. I'd probably go HP tuners as well. Oh yea, 3 bar map sensors and harness kit. etc. That's what you'll need to go above 400. Goodluck n welcome.

 

if ur car is on stock turbo, i recommend u drop the boost to about 22 psi. 26 is out of efficiency and u will do what so many others have done and blow ur ring lands. the air is to hot.

 

welcome and congrats on the 'balt!!

 

Yes you are boosting way too much.

Trust us on this. 22 or 23 is the reliable range.
