I have a 1999 firebird formula m6
My mods are slp loud mouth1,slp flow pack
lid, smooth bellow, k&n air filter, cold air induction.
I had a ls6 intake put on, and my car was tuned I
making 326.8 rear wheel hp and 343 torque.so I gained
10 rwhp form the ls6 intake and 11 rwhp from the tune.
Do these numbers sound right for what done to my car.Thanks!

I was told by the previous owner of my 00 m6 Z28 with LT's, ORY, gibson stainless catback, Volant, a tune my car put down 346 rwhp..........it also has 410s but i doubt that would reflect any on a dyno

With LT's and tune I went from 306HP to 349HP. Don't doubt the power of adding headers.

or ARH Headers with catted y My goal is to get about 400 RWHP

With headers compared to your LS6 manifold I made almost 10 more rwhp and 2 more rwtq. Im also doing an LS6 manifold on Tuesday and Im shooting for 360. To kinda give you an idea of how bad the stock manifolds flow. Headers will make a huge difference. But nice numbers for few mods.

Thanks for the reply, thank you for everyone who put their info in. My next step is to put american racing or cooks long tubes headers in my car. What do you think my gains would be putting in the long tubes and getting my car re-tuned? I'm guessing 20 more hp.

Headers should definitely be the next step, especially if you plan on getting a cam to reach your goals.

20ish seems possible...Depends on the car, you never know.
