Dyno tune in SoCal

I need my wifes 04' 5.3 Trailblazer tuned. It lacks a ton of power belowe 4000rpm. Not good on the launch ramp.
Anyone recommend a shop in the Corona, Riverside area?
Purchased a Diablo Predator, worked good for sift points and high rpm power, did nothing to the torque managment.

Have you used them?

Steve Cole knows his stuff. Just South of the 91 at Central. He has off-the-shelf programs for this stuff though. Just tell him what you want.

Cunningham Motorsports is excellent, so is RPM out in Canyon Country, CA. Wanna have some real fun, change the cam to a small duration 208/208 or a 208/212 @.050 with some decent lift, .550 lift on a 112lsa and watch the low end torque com waaaay up! If your willing to go into the motor, that is

Will the cam swap pass California smog laws?

That size cam will pass smog easily. Anything under 218 on the intake side will pass easily, as long as its tuned properly. A 208 or 212 grind isnt much larger than your stock duration, but the .550 lift is quite a difference. Good torque cam for trucks and suv's, still pulls strong to 6000

So, anything else besides a cam and tune? Looks like I can't talk my wife into trading up, she loves her Trailblazer. I'll probably be owning it for a while. When the time comes, and it will, I'll sneak this stuff in while doing a major repair
How much hp and tq gains can i expect? Right now the specs say the motor is good for 290hp, don't see a torque curve.

Bruce at CBM did my off road car and he is a stand up guy. If he cant he knows who can.

You can keep her in a trail blazer, just get rid of the one you have and buy an SS. Just picked one up a few months ago. 400hp LS2 and AWD. You will have no problems at the launch ramp or anywhere else for that matter.
