Default Anybody doing mail tunes?

I'm looking to get a tune for my Olds, long story short, the 1998 LSS is unsupported by either HPT or DHP. Managed to get the PCM unlocked for tuning, and have a local dyno tuner on standby, but I do have the ability to scan and write with DHP and was considering getting a seasoned 3800 veteran to do the tune, maybe VIA a sharing hub. Dyno tuning is $160 an hour, and he would be willing to use my street scans to tune to save some cash, but I wonder if it would be a better idea to source from the 3800 community for this. I have full confidence in his abilities, but I would think the 3800 stuff might have special considerations.

I'm not looking for a streetsweeper tune, I just basically want to deal with the ridiculous torque management, shift points, and optimize the engine tune for my mods, as well as some deletions, VATS, post cat O2, etc.

Any suggestions are appreciated, I'm dying to get this now.

Kevin

Why is the 98 LSS unsupported by HPT? My 97 Bonneville is supported.

But because you have custom mods, mail order tunes won't work very well in your environment. There is no such thing as a cut n dry recipe for tuning. That'* why all tuning must be done on site with the car. Scan, scan, tune, scan, scan, tune. etc. If it was just a basic VATS, TM, fans, speedo, tire, autotrans delete, then that'* one thing. But if you want to adjust for a different MAF, or SD, then you will need to have a scanner on site. Because you have DHP, not everyone has DHP, which means, your scans will not work with HPT and vice versa, because with HPT, you can actually COPY and PAST data from the scanner and put it into the editor.

My assumption is that with only about 5000 produced in '98 with L67 it wasn't worth it.

I'm aware how vital scanning is, but I thought I could provide data and the file could be tweaked by anybody. Obviously it'* not as fast or convenient as an in car, but I'm pretty sure it IS possible. Coincidentally, the tuner I have already sent scans and a .DBF file to has apparently gotten his HPT dongle to allow him to do this. Just saying...

no one makes a software that you can cheaply just load a program from your pc to your trucks pcm. you would have to buy the hpt program, which is 5-600, or you could just eat the deposit on the tuned pcm if its more than the return shipping. then you can keep your original pcm and put it back if you have to take it to the dealer or want to sell the truck

i guess they do have email tunes now but its as expensive as the hpt software that will let you tune it yourself, and you still have to have the cable shipped to you

Some of them do email tunes, and most others don't because they don't want people copying their work. So they have to tuner lock the PCM when they program it.

Either way, your paying big bucks for your own tuner, or your paying to have your PCM mailed/returned. Even then I recommend NOT doing that. I am a firm believer against mail order tunes.
