Left or right?

What's your tire setup?

Left lane, running ET streets at 14psi

There is something wrong.....

Ouch.

Nice! I can't wait to get my ls car done.

I agree, it's not mph'n like it should. I just pulled a 1.68 60' and a 7.50 1/8 mile but missed 4th

It's on E85 too ?

Wonder if something is a restrictor on the engine (heads/intake/cam) or if maybe it's the tune.

Yessir, I have an issue with 4th gear and I'm getting extreme amounts of KR. We shut her down and nhra fed home, best 1/4 is 11.8@120, best 1/8 is 7.5@94 .

I see them heads being the issue even once you get your tune straight......that much cam and that much cubes......Ported 243's just aren't going to cut it

I need to take a look at some logs. I'm seeing IAT's over 200 and lots of kr. Car got slower and slower over the day, best pass was the first pass. Disappointed for shure, I had a dead hook pass leaving at 5,500 and it caught me off gaurs so bad it yanked my foot of the gas. I have an in car video of it, I'll get the passes uploaded and let you guys take a look at it.

agreed on the heads. Hell, you are at the edge of what ported LS3 heads can cover properly. One other thought: if you are still running a maf, are you running a vararam? have you checked your maf readings while wot? from my experience data logging will not show up the fluctuations that happen when there is maf cavitation. You have to have someone watch it live on the display screen of a laptop to see the voltage slamming back and forth from zero to five when it starts cavitating. I lost over 50rwhp from that and never knew it until I went with a svede and the car felt like I picked up a small shot of nitrous on the top end.

^ great point sticks, but I'm SD. I'm not sure what's going on. You guys think maybe I'm floating valves? It's a pretty radical cam and I'm runnati lunati Duals.

Your heads just simply can't move the air that intake and that cam/Cubes want.......It's running as expected to me now that I seen a full list of mods, a good set of heads will make that car feel like a brand new car

Good run with wrx...but ya something not right. They may be on to something with the heads.
