    what did they tell you to expect? I've never used that company before...did they say tunes usually net you 10hp...? 15hp...? 20hp...? etc?

    You have no mods basically. You probably picked up maybe 10hp-20hp if that. Mail order tunes aren't spot on unless your datalogging a lot. You basically got a tune that kinda worked in someone else's setup that had close to the same mods as you.

    Just a note -- if the PCM for Less tune modified your transmission line pressures... and you added a modded valve body to your transmission after the fact, then you are probably running some pretty high line pressures. I had this issue when I installed a Performabuilt Transmission and failed to adjust my tune to back things down a bit.

    They claim up to 25 HP. I was realistically expecting 10 but felt no difference at all.

    On a totally stock setup, my understanding is that a tune will net you around 10-15 hp. With aftermarket components, such as headers, exhaust, intake, etc. then you can see something greater. I will say that the tune in and of itself did not result in any appreciable change per my "butt dyno", however, the engine did feel more responsive and the shifting on our A4 was definitely improved.

    Really suggest you consider using Frost for your next mail order tune. Using someone who really knows the LS engines versus someone who has a catalog of "kind of right" tunes can make all the difference.

    The thing is since I have a 95 it is an LT1. Does frost know them as well as the lLs1's ?

    this caught my eye too.....if they raised the line pressures it's not a good idea to then also run a shift kit.

    You are right, my bad. Frost does not show LT1s on the web site. I'll go crawl back in my hole now. Someone poke a stick in when its spring.

    Mail order tunes are always much more conservative than in-house. Alvin and his guys/gals at PCM For Less know their stuff, but they are car guys too, and they don't want to blow up your car anymore than you do!
