What are your mods? What do you mean slower? Slower at the track or butt dyno slower? Who did the tune?

I don't mean this in a negative way, but mail order tunes are only good enough to get you by. I had a mail order tune done by Frost and granted the car ran and drove fine, it was sub-par to what you can get on the dyno. I suggest get a real chassis dyno tune. Most mail order tunes are tuned to the "safe" side. Like timing will be dialed back...its like that to protect you.

Never tuned a Camaro, but have tuned a few ls engines over the years. Yeah a mail order tune is basically a generic tune that is considered to be incredibly safe.

I bought the HP tuner kit years ago, the only way to tune an individual engine to run the best it ever can, every engine is slightly different and may respond better to individual mods.

Don't no what they charge for a mail tune....... but the HP tuner kit and wideband cost me 1200 dollars I thin,k and comes with enough credits to do three cars.

Compare the DA to your best and newest pass. You likely did not really get slower.

1.4 mph is nothing to fret about. Track and weather variances can fluctuate trap speed.

They lowered 2 to 3 shift point to 5800 it was shifting at 6200

Any reason why? Are you going to bump it back up to 6200?

seem like it was out of power when it shifted.. just wanted it a little lese like to 6150 but went way down im gonna have it put back to 6200
