with the m62 supercharger and without nitrous that will be a VERY hard goal to hit. I have been on that quest for years and still haven't hit it. I am well over 300 with the nitrous, however without it I am currently in the 280s. I am still going to need to port the head and run some cams for that top end power.

Anyways, since you have high hp goals, go with a custom 3 inch exhaust. It's so much cheaper then buying a company exhaust and sounds absolutely amazing!

That's my goal as well. I'm goin 2.6 pulley, 60# injectors, tune, H/E, dual pass, option b, meth, poly tranny and motor mounts, and an Exedy clutch/flywheel combo.

i might do that..i ran across a shop that wanted 400 for a 3' turbo back dual end on my srt4 so with this car it should be much cheaper. I would think

HpTuners...is it worth it? do they come with a canned tune for stock cars to produce more hp?

If you plan on doing mods a little at a time and you know how to tune your car it is. If not every time you add a mod you're going to have to go pay to get it retuned...

That's not true at all. You don't need a tune every time you go put on a mod. That would be retarded. You don't need a tune for any of the cooling mods besides meth/water injection. You don't need a tune for a cold air intake, header, exhaust, etc. It helps, but its not needed. The only thing you need to tune for is larger injectors. 42lbers or 60lbers, whichever you use.

I recommend building the car up, and doing the injectors/pulley and tune last. If needed I can tune you. I recommend hptuners for everyone! It's very easy to learn in my opinion, for some its not, and it can help you with soooo many things!

That's kinda what I said earlier...Do the supporting mods first then go for the HP adders...

Zach06CobaltSC

I was just saying that you dont need a tune every time you do the mods. The order the mods go in isn't a huge deal. However before pulley swaps are done, cooling mods should be put on.

The only thing you need to tune for is new injectors and nitrous and meth/water injection.

update: I am throwing code P0171 bank 1 lean....

So what am I looking at here?
my rpm's are hanging a bit as well..
