Real nice! I haven't been down there, but I've only heard good things about Speed Inc.
If I was keeping the car another year or two, I'd probably head down there myself. |

When you say the octane tune is switchable, are you saying you have to load the tune or will the one tune adjust based on octane used detected by a sensor? Except heads, it's pretty much the same mods I keep thinking for myself. If you don't want to post it, can u pm me an idea what your mods with labor cost you.

Video with corsa xtreme cable back exhaust installed. I’m so happy I went with corsa! Absolutely no drone while cruising and I love how it screams and how angry she sounds. It also woke up my car while idling. Amazon had them for sale for $1,100.00 and free two day shipping.

Wow, that idle is very nice, almost like stock. Do you know if it would pass emissions with this cam?

It was like that with the stock mufflers. It much rougher now with the corsa xtreme but I love it. My car won’t pass emissions because I don’t have cats but I don’t see why you won’t pass it if you had cats.

Awesome build! Why didn't you go with the roto-fab big gulp?

When I got this build done the big gulp wasn’t out yet. I have it on now and I picked up another 20rwhp on 93 octane. I did not see any gains with the 100 octane tune. She will be back in the shop in two weeks to get a FI interchiller installed!

How did they set up the switch between 2 tunes?
