My car build/journal

ATS Racing in Denton, TX hosted a dyno day today which was awesome.
Had quite a nice variety of cars show up, several stock cars, a couple turbocharged and supercharged and guys like me running a variety of bolt ons and/or E85. It was a fun time. Also I got a ride in a turbocharged BRZ and that was awesome, now I want boost really badly :P
My car put down decent numbers, but it seems my headers and front pipe don't make much of a difference as a stock car on E85 made about 1-2 hp more than me. I did have a slightly smaller torque dip though but it seems like for an off-the-shelf E85 tune exhaust mods may not add much performance. Here are my runs:

I completely forget what I was originally trying to search for (something related to AFR's and tuning?) but I happened across two unrelated posts that were about getting popping/backfire on decel and so I tried it out. It's ridiculous and funny and lots of fun. Here's what it sounds like.

Switched back to a 93 tune, doesn't actually feel slower than E85. Maybe a little less low end but not real noticeable, need to dyno and see how it compares.
