GIVING UP ON JET DST FOR 1997 CAMARO LT-1 WHAT IS THE BEST TO TUNE WITH?

I've had it with my JET DST as it stopped communicating with my ECM. I tried 3 different ECMs thinking I had a brick
and of course there is no customer support. Good news is I am getting a full refund from where I bought it over a year ago!

My challange to all is what is the best? HP does not support me vechicle.

I want to buy the whole package, software and cables.

Your help is greatly appreciated. RK.
