That's it. The HKS RS intake could account for a little more power than a standard filter because it isn't even really a filter. It's just JDM jewelry that clogs up the intake manifold with dirt, but it is less restrictive.

 

What octane fuel?

 

those numbers seem really low for 9. when i first got tuned all i had was Exhaust, Test pipe, downpipe, MBC, and intake and it made 352 hp at 23- 22 psi

 

I just use 93 from the pump.

 

I checked it out, I think if I had a little more aggressive tune and bump up to 23 psi I would have no problem making 350awhp.

I like the safe tune tho.

 

Nice numbers man, gives me an idea of what I'll run once I get a dyno tune.

 

If I keep my car, I will go further with mods, otherwise I am going to return it to stock this summer and sell. I still have a full warranty, they haven't flagged me yet.

 

I'd stick with the less aggressive tune. Better safe than sorry. I hear stories about how some guys make 500 WHP on a car...for a few minutes...and then go back to the safe tune, but still print out the dynographs of the "dangerous/risky" tune for bragging rights. Kind of silly really. I'm more interested in what combos of mods yield what rather than breaking certain power milestones or barriers.

I have my warranty too!! They're replacing my factory cat this week.

 

my 8 makes roughly the same exact numbers with the same exact mods....they do seem low for a 9

 

yup definitely low

 

Believe me the numbers are fine. Most 9s get tuned to 23-24 psi to achieve the higher numbers mentioned. You have a safe tune and the powerband looks good.

 

Thats what I thought for just TBE, MBC, porting with tune @ 21.

I am considering reflashing at 23psi and adding a k&n drop in.

 

With that I wouldn't be surprised to see 15whp and 20trq extra.

 

they do seem kind of low for all the porting you did. Turn up the boost!!

 

pretty nice torque curve buddy.
