2003 Blazer 4.3 - Need Help Tuning

[Pro]

Hi all,

I'm new to the forum, and completely new to vehicle tuning.

I was just given a JET DST tuner for increasing the horsepower on my '03 Blazer with an LU3 4.3L V6, but I do not know where to start when it comes to tuning the vehicle to increase horsepower.

I know the question is a little vague, but I'm having a really hard time finding anyone using a JET DST tuner, and didn't know if the tunes were usually listed as binary files, or if tunes were usually just spec'd out so that people with different tuners could use them.

Thanks

Most (all) people here are using HPt which is more indepth of tuning solution.

If you have both you could put the jet tune into the PCM and then use hpt to download it and examine it. Some of those tunes could be locked? I know you get alot more control with hpt and that steers people here.
