the Brenspeed tunes are kinda interesting. the 93 tune makes insane power, but...........its more of a race tune, not as well suited for daily driving. its kinda touchy and sensitive to bad gas..............you have to get great gas and it can't be over like 100 degrees out or it pings on the top end, ask around, some people have gotten this problem. its a great tune to have in your arsenal though......i really just use it for the track.


for daily driving, i use the 91 tune with 93 gas. great low end-midrange grunt. more fun to drive every day.

I just got the Bama 93 Torque and 93 race tunes and haven't tried the race yet but the torque is noticablely more powerful and seems to work good daily

I use the 87 for DD'ing.

The 91/93 seem to have a rough idle when the AC is on after multiple retunes.

Brent makes a damn good tune though; either him or Bama.

There was a third tuner, but people don't seem to use him so much.

Don't get the GMS CAI with the tune chip. You are totally stuck unless you drop even more money if you ever want to do anything else.
