Default Dyno results

Well my best run is in my sig, high 12s at 105. I ran that with an open Y-pipe. For the dyno the Y-pipe was connected to the rest of the exhaust, which includes the stock 2.75" over the axle pipe to my 3" magnaflow. I have pacesetter LTs, ORY, and a cai for power mods, besides the free ****.

I got 285/320 on a dynojet. Best out of three runs, took it to 6K and tapped the limiter. My A/F was 11.8:1, it just went richer than **** when the car hit WOT. I think the car leaned out with the open exhaust which explains why it ran so good at the track.

Wonder what I'll get with a tune?

thats a very good track time for just lontubes/ory/cold air. weld a cutout on there after the y and see if that improves the dyno numbers.

Well that's my only power mods. I also had mt et streets and lcas on those runs.

I'm sure the A/F is what's f'd up. I just took the exhaust back apart and it feels like it has a ton more power. With the exhaust corked up it won't hardly spin the tires from a roll in first, with it apart it lights them up big time and pulls much much harder. I'll get a tune and redyno it after I get my exhaust redone (full 3" with powerstick muffler).

Some pretty good dyno numbers, get a tune on there and you should be over 300rwhp. How many miles are on the car?
