dyno numbers seem low I just dynoed my 99 z28 with pacesetter l/t, o/r y pipe, B&B Triflo catback, K&N fipk, and all the free mods and put down 316 hp and 332 tq to the wheels, doesn't that seem low for an ls1 with headers? My air fuel ratio was at 12.8.

Get your car tuned. Something sounds amiss.

I would also suggest a tune if you plan on staying stock internal for a couple years.
If not dont waste your time on the dyno tune to pick up 10-20 horsepower for 500 bucks. Unless that is worth it to you. But it is kind of a waste when you will need to tune again if you do a cam or h/c later.
I drove all last summer on a 224 cam only on the stock tune. I knew I was going to change the cam and add heads the next year so I didnt waste the money.
