before & after dyno numbers

[KingSnake97]

Numbers not bad from what I can tell.
My 97gts with Side Exaust, Tri-y headers, Btr air cones
436.5rwhp @ 469.5lbs.

Although I think the T&D's should give you a few more HP.

I think your car should be making more power, maybe more like 445-450rwhp. Try adding the front air box mod "without rain baffle", i gained 7rwhp/5rwtq from that simpe mod and costs about $150-$180.
Drive the car for a while, and get rid of the check engine light, and dyno the car again.

steelgts,

Impressive numbers. I sent you a private message concerning cost, etc.. Thanks for any advice you can give me.

Interesting.

I dyned 02 GTS with 1300 miles K&K+ s tubes + Corsa at 430RWHP and 468RWTQ. When I took the cats off I lost 6HP due to car runing very rich (fat). I'll be getting O2 sims this week and will dyno again and I should be at 450RWHP mark. Next is Sean's VEC1 which should give me 5-10RWHP. I'll post my results.

O2 sims should help quite a bit. You are running really rich without them.
