thanks dude.

 

what's your altitude inferno? My car never got to 80kpa here at 3500-4000feet. stock.

 

wow man spaz, i hit 80 kpa no problem and my altitude on average nights is about 4500 ft, and than as well even in calgary i hit 80 kpa, i think my car is a freak, hit 21 with a 2.6 so on, lol

 

my altitude here is 1220ft

 

Thats crazy high man. You don't list it, but I'm assuming you have full exhaust work done. I'd get my head ported while you had it off to put in the new valves. Seems like you got some restriction somewhere, and since you changed the pistons out (and I'm assuming the exhaust), that would most likely be where your problem is.

 

I hit 100 kpa

 

do you have any mods though?

 

Only Stage 2, CAI, Cat-back, & a honed manifold

 

100kpa is about right for stage 2 with the other mods. Would be about 105kpa if you didn't have the exhaust work done.
