+1 the tune needs to be spot on if your going over 420-430...i ran 11 psi with no problems for about a year and a half.

Well if you find a great tuner and keep your A/F safe youl be fine at 450 RWHP!

+1 meth is the right way to go if your wanting more power while staying on the safe side.

Let Bob add Meth and a flip tune. I do suggest you hook up a fail safe LED in the interior if you do the Meth kit so you know if it's working. He can even hook you up with a pure water tune.

MAKE SURE EVERYTHING IS MECHANICALLY SOUND ON YOUR CAR THOUGH.

well, ive already talked to bob and he told me it would be alright. I just thought i'd see what some of you guys are doing. I already have a meth kit so im not worried there. The car only has 36,000 miles on it so im sure the motor is "alright".

Im not worried about bobs tune being off at all!!! i think im going to go ahead and do it...

i think you guys didn't look and see that guy had an 07,( the guy who said hes running 500+) the 07s can handle more boost/power on stock internals, there are quite a few running around with 500+ on stock internals, i wouldn't push that for a day in a 99-04.

I guess the Altitude helps me out as well.....Fort Collins Colorado is over 5600' and the local Drag Strip is at 5800' Bandimere Speedway

Something we failed to Realize about KuRUPT K is that he has an S197. Those engines although have the powder rods like ours are still able to handle more Boost and Hp because of the 3v and the new piston coating they have.

Although, he's still pushing it past what the S197 guys normally do as well.
