300hp-350hp goal

[Ripcat]

Hi im a new 2006 redline owner and want to mod my baby to 300-350hp range pref without tuning. I have just started with a cat backed magniflow exhaust. Any one have any suggestions for major hp preformence mods?
Im looking for gains of 15-20hp min

thnx in advance

oh also is there anywere that sells body kits for the red line 06 i've been able to locate 2 and there both ugly as sin

I don't see how you are going to get that much power without tuning. You are going to need to add a lot of fuel and the stock computer won't do it.

Check out http://www.intense-racing.com/Mercha...ry_Code=LSJ_PP they have a Stage 5 kit that makes around 275 whp and 275 wtq for about $1,000.

You're definitely not going to come close to that goal without tapping into the computer. You need a stage kit of some sort to get even close and then you'll be tearing into your engine, shaving heads, porting things, different pistons, etc....Have fun!

Does getting a flashed PCM from INTENSE count as tuning as it is pretuned? If not, you're on crack! Without any form of tuning the PCM, it can't handle 42.5lb injectors even!!!

Try getting the 60s on there without a flashed PCM...your spark plugs will be gone in a day...trust me, I know. My PCM is for the 42.5 and I have the 60s now and I am running rich.

You might be able to do 300 w/o internals and w/o nitrous and with tuning.

You can do it without N20 and the stock internals, but not without tuning...

You need tuning done, no way can you hit your numbers without.

I had Intake/Header/Exhaust, 2.8" pulley, GM stage reflash + 42.5lbs injectors and I don't think I was past 260whp.

Echo? w/o=without...

In what car can you increase power output by 75% withOUT any form of tuning? I'm just wondering where you got the expectation from, that's all.

after u throw on a pulley, and breathing shit, i/h/e, ur alrdy maxing out the stock in jectors, bigger injectors = more fuel, with our pcm and almost any car u need tuning for more fuel and such
