OK LS1tech guru's I've got a challenge for you..... Getting my car re-tuned this Saturday and I want to see how close you can get on my power.

Old Dyno was 340 Rwhp / 350 Rwtq

This was my 98 Z28 with Auto and 3200 stall, MTI B1 Cam, MAC midlength headers, Off Road Y and Bullet muffler dumped, Lid, Free mods, NGKTR6 plugs. Not too bad for the auto and stall.

I added stage 2 ported heads milled .050" with 2.02/1.57 valves and the LS6 intake. Just want to see what you think that will get me at after a good Dyno tune. I know the auto with stall is a substantial loss on the Dyno, but I gave you my first run and mods for reference. I will post results Saturday afternoon. I am not expecting anything great, just wondering if I am par for the mods I have in my A4. Thanks everyone

 

385-395wrhp Those tr6 plugs might be a little cold if your not running juice or a blower.

 

I thought about getting some hotter plugs, but I do run a small shot on it. So just to be safe, I am keeping the cooler plugs in there

Thanks for the input.
