Longtube headers, hi flow cats, stock catback, cold air intake and a tune..

What is "the norm" for dyno numbers?

Matt you left out some mods. It's longtubes with cats, xpipe, stock mufflers, cold air intake, 160 thermostat and tune.

I made 359hp and 373tq with Dynatech headers w/hi flow cats, rotofab CAI, stock exhaust past the cats, with a tune and a 3600 stall.

Put it on the dyno before the heads/cam and it made 379 hp and 402 tq. Mods were custom mid-length 1 3/4" headers with no cats and full Magnaflow exhaust, ADM CAI and tune.

Just dynoed the car again today without the resonator with x-pipe replacement and it made 376hp and 384tq.

My car made 381 / 387 with the mods in my sig and stock mufflers. The tune came after the intake but before the headers. With a good tune you should be right around 400 depending on the dyno.

That sounds low. You might want to look into pulling your ecm fuses to reset your cpu. Some of the l99s would go to the low octane table if filled with reg unleaded and wouldnt switch to the high octane table after filling with 91+ octane.

Just remember that not all the dyno's are created equally. Depending on the dyno they will all read differently.

I totally forgot I even started this thread and I'm just not checking in on it. From what I see here and what I've seen on other boards your numbers fall in line with others with automatic cars.

Dyno=doesn't mean crap to me. Track=does. Like yesterdays numbers didn't impress me either but whenever I get time to go to the track I'll see how it does. Especially since I think the tint will pick me up like three tenths.

Good point, but if you use the same dyno you can measure in some way what each mod did for you HP/TQ even though it's just a number because they all seem to spit out a little different numbers from what people are saying.

May L99 made 340rwhp and 362tq on a Dynojet with a X-Pipe, Magnaflow Axle back muffler delete and a small tune. This was in 4th gear with convertor locked. I have scene people dyno in 2nd and 3rd gears and claim crazy numbers.

it would be nice if it was actually 425 to the wheels stock...

Mine is stock and I feel like i could pick up a few ponies.

Thought about getting the TSP exhaust system and a CAI.

Do you think tunes will void warranty stuff?

it depends on the dealership, but 99% yes a TUNE WILL VOID your warranty

I would say between 370-380 to the wheels. I am waiting to dyno my car with about the same mods.
