2001 Firebird WS6 Dyno (few mods,listed) I Have 2001 Firebird WS6 Automatic
Mods: LS1 heads(a bit ported), COmp Cam 212/218 .522/.529 114, LT headers, SLP MAF, SLP Cold air intake
DYNO RESULTS: 349rwhp 407rwtorq
The car was running lean, at full throttle 14.3:1
I will be tunning the car with an HP Tuner or EFILive
BUT I WANTED TO KNOW IF THOSE NUMBERS ARE ACCEPTABLE FOR THAT MODS, BECAUSE I WANT TO BE SURE THAT EVERYTHING IS WELL MOUNTED.
SINCE I HAVE READ SOME CARS WITH LESS MODS BUT MORE HP

I would say on a tuned car the HP is low, but that's a very small cam. I've seen larger cams put out in the 360s, but I think tuned that setup should be somewhere in the 360 range, anyways (the A4 is going to prevent you from seeing great numbers most likely, but that doesn't mean it isn't going to perform well). I would make sure to tune it before anymore dyno runs. Did you get an A/F reading when you had it dynoed? Gotta make sure it's safe before beating on it.

Yes, at 3000rpm the Air/fuel ratio was 12.1 but 4500+ it goes to 14.3.
I aint running the car right now because of that.
It is posible for a car with only that rwhp to go to the AF ratio or can i have a problem with some sensor?
RIght now i am without catalitics but i bought ones from SLP for LT headers.
And also, i bought that small cam because it didnt need the PCM to be tuned, but at the end, with the other mods i will have to doit, so i am really disapointed with that purshase. If i knew this will happan i will bough like a 224-230+. But my interest is to have a dayli car the moves well.

Hey but thanks a lot and and if you have any other recommendation, bring it on.
And i wanted to ask, do you recommend more HP Tuner or EFILive? And if tuned by a dyno guy with wideband, can it harm my car anyways?

your car leans out over 4K because after 4K all fueling comes from the MAF, and you have an SLP MAF that you are not tuned for. If you go back to the dyno before getting tuned swap out the MAF for the stock one and your AFR will be closer. Personally, I'd run the stock MAF until you get it tuned so that you won't be so lean.
