Install was pretty straight forward. Made me abit nervous when I first fired it up((91 octane Perf. tune). Car didn't want to idle and was popping thru the CAI. Motor killed. Fired it up again and it ran rough was still popping but this time it kept running. Slowly it began to smooth out and quit popping. Pretty soon(2-3 minutes) it was running real smooth. I guess it takes abit for computer to adjust.T hen I put in and out of gear(automatic) and after a couple of minutes I turned on the A/C to put an extra load on it. Guy at Bama suggested that so the computer learns to adjust. Then after about 10 minutes took it for a ride. Ran real nice. The first thing I noticed was the shifting of the tranz, Each shift was very firm and positive. Not harsh or jerky. Same when it would downshift. Watched the guage and info. readings . All readings were the same as pretune. Everything normal including the air/ fuel ratio. All in all I'm very pleased. Throttle was very responsive. Have'nt tried the 91 Race tune yet. Save that for my next trip to the track.Ran it stock and had a best of 12.92 @109 last year. Looking forward to seeing the difference.
