Just Wondering Why

[Flad]

My 03 has a catback and intake only.

had in on a dyno jet the # are 382 hp and 328 tq.

do these seem low?, Any ideas, why the numbers are low
FYI
I'm the second owner, bought it in 06 with 4500 miles, it just hit 20,000.
Owner one which I know kept it stock.

Did you tune it or just throw it on there to see what it makes? Put a 2.76" pulley on it and get it tuned. Should put down 455-475rwhp after a pulley and exhaust. I don't think id sweat too much if you haven't tuned it yet. Bone stock they make on average 360 rwhp. So you picked up around 20 without a tune.

the torque seems quite low, hp seems ok with the fact that it's not tuned. get a handheld and you'll pick up some nice numbers, or throw a pulley on it too and be really happy.

No it does not have a tune,

The 328 seems kinda low, for catback and intake.
I was hopping there may be something that could be done without tunning

you can blow the motor without tuning...thats something ;-D

HP is good, tq is a bit low...but thats easily remedied...wait until you can afford a tune before you do too much more.

^That's what I thought
