I am very impressed. Car feels stronger and shifts MUCH better. Just what I expected. I haven't put very many miles on it since I got it back but right now I'm very happy!! I will post some more long term results after a few more miles and a mpg check. I would recommend them to anyone interested in a mail order tune!

I had ECS do a mail order tune for me after my header install. THIS IS A MUST FOR 99.00!! The difference is amazing in the shift points and the way the car runs. I highly recommend ECS for this tune. You will be very happy.

I had my A4 done by Doug at Carlisle 2 years ago. It was a totally different car than the one I drove up there, when he got done with it. He changed the shift points, re-set both fans to come on at 200*, and whatever other voodoo he does.

If you are considering having a mail order tune but just not sure about it...don't wait any longer. This is the place to send it. I removed it just like Chris said, there is a little 7mm screw way up the inside of the fender next to the door he said makes it easy to remove without bracket breakage, and he was certainly right, also makes it a whole lot easier to see the rest of the 7mm screws holding everything in. It was out in less than 5 minutes. Just got it back and a total of 12 minutes from the time I sat down on the garage floor till I cranked it up. Done and what a difference. LT headers, X-pipe, CAI, and GHL Bullets round out my mods so far and this was the best small chunk of change I've spent ! Don't delay, just do it, it's worth it! The best mod I've made, especially for the buck. Big seat of the pants difference. Now, it runs like the sports car it truly is. I'm impressed. Especially with the A4 and the way it shifts now. Yes, you can really feel the difference.

I have an ECS m/o tune. I'm right about 5000'. My fuel milage has gone up about 1.5mpg now. No detonation, no SES. I specifically asked about high altitude applications and felt it was important. I always thought altitude played a part in computer adjustments because of a difference in atmospheric pressure.

I finally got my PCM back in and tested everything out with the new headers. The car is a beast now! I was amazed at the difference (a buddy of mine was also). Anyone on the fence I would strongly suggest getting off and sending your PCM to ECS. They do great work. Thanks guys!!

Hey Everyone: I'd like to vouch for Doug's tunes...! I actually just sent an email to Chris at ECS about my car. I had the chance to drive my friend's H/C '01 C5 recently. Great car and it's fast, but my car actually pulls harder on the bottom end. Part of that is the movement of the torque curve with his cam, but I know a lot of it is this tune as well. My buddy also drove my car and said, "I wouldn't do anything else to this car," as he knew I was thinking of putting in a H/C setup. The car is really that fast. All I've done to date is Kooks LT's, a Vararam and Doug's tune. Great job, Doug...! Rossi, Pittsburgh PA

I drove a from Long Island to south Jersey, a little less then 3 hours to have Doug street tune my 99 FRC on a day that they are closed. Doug did and a great job with my car and I am very happy with the results. The customer service is outstanding. I give ECS two thumbs, Thank you ECS.
