other than that stock

13psi of boost

the car barely passes smog
yeah that dam smog thing in cali sucks

 

It sounds ok.. a little bit low. There are guys making that w/intake and a pulley. But it doesn't sound TO off... I mean my #'s were 440/480 with just a catback, pulley and tune.

 

might be a little low since you have headers

 

Your boost is a little bit low but that is because of the headers, but you overall rwhp seems low especially with the mods you have. Who did you have tune you car?

 

it was all bought this way 15k on it
the dyno was done at swanson performance some place in LA
swansonperformance.com

 

seems right with 91 octane

 

I think it sounds fine. You have a bunch of mods that aren't going to do anything for what you have. Headers are pointless at your power level, TB/MAF won't help much until you are ported or have a twin screw. So basically you have exhaust, intake, pulley, and tune, for 450 RWHP, which is right.

 

I disagree with the headers not making a difference.. he should see a solid gain from the headers.. the stock manifolds are good, but they're not great... the longtubes should DEFINATLY open up some more power on the car.
