    Who's HP Tuned?

    I've got the opportunity to get tuned by a pretty knowledgable tuner who's got a 300 hp Ion Redline and a Cobalt that's in the high 200's. He says he'll tune my car for the cost of the license. Is it a good deal? How does the HP Tuners differ from a DHP tune? Has HPT come up with an equivalent to DHP's performance shift?

    BTW, I've got a 2004 Monte Carlo with the 3400. I've got headers, intake, SLP catback, poly engine mounts, 62mm TCE TB, Ported Upper Intake, and a DHP V1.0 PCM.

    I would like to purchase a powertuner, but with this being my daily driver, I'm afraid I might mess something up. And that's why I'm sort of leaning towards letting this guy do all the work.

    If the license costs less than $200 and he is going to make a custom tune for your car then Id say its worth it. Learning to use a tuner yourself will take some time and effort, plus the cost of the tuner and a wideband which will easily hit $500+.

      Yeah, that's what I was thinking. My main reason for wanting to get it done was to have something a little more custom than the DHPv1.0 and I'd like to get the most out of the TB and headers.

      I have no problem spending the dough on the powertuner, but I'd like to be able to work with someone, in person, who tunes. I think I'd learn better this way versus reading in the forum.

        He won't be able to do anything besides read that PCM. You already have a DHP PCM, so the HP Tuner can't do a thing with it, as it is locked. Only a DHP PowrTuner can edit that PCM file.

        One way around that MIGHT be to take and read that PCM, save the file, get a factory PCM, swap it in, and then write over it. I'm not sure that the HPT can read a DHP file, though. Or, you can just start over with a factory PCM, and go from there. Sell your DHP unit, to cover the cost.

          I've still got my factory pcm. Can't the DHP pcm be flashed back to stock? The only thing that's turning me away from this deal right now is the lack of performance shift.

            I think what would happen if you took and reverted the PCM file back to stock, it would still be a DHP file, though modified to stock, rendering it readable still ONLY by DHP hardware.

              Oh, well it's whatever. I figured that if it was possible for the dealer to flash it back to stock, then this guy could too. Even if it was still only readable by DHP, I'd just program the stock pcm. Well, I've got some deciding to do. Right now, I'm leaning towards saving up and getting the powertuner. It seems like a bit of a waste, but I should be able to sell it for relatively close to what I paid for it once I'm done tuning.

                You'll never be done tuning! LOL

                Just put the stock PCM back in, and have him work it from there. Sell the DHP unit.

                  I got the HP Tuners software before they went homo fag queer with their pricing. I like it, but to get the full advantage out of any of these tuner quites you really need a PCM that's newer than 2000. The older computers just don't allow you to do enough.
                  I may own a GTO now, but I'm still a 60V6er at heart.

                    I think I may get a powertuner and work with a guy I know in MD who also has one. He's got a NA 3800 Monte Carlo with a cam, heads, pretty much the whole works short of getting blown. He's got a wideband too. I've got a 2004 Monte carlo, so I don't have an old pcm. Like I said, I'd really just like to take full advantage of my current mods, maybe throw on the 3500 Upper, and maintain my performance shift mode. If I can get all that, then I'll be more than satisfied.
