2002 GM 4.3/4.8/5.3/6.0/8.1 Trucks All Trans 30012

I bought this 33 days ago (per the receipt) so it's as new. All boxes, manuals, receipt, etc. Read about it at the above website (Hypertechs).

I bought this from Checker. Retail is $419.95 at Checker.

$290 shipped to your door fully insured.

Why am I selling? I have a upgraded STS Turbo kit on the way and will need a custom tune. My loss, your gain. This thing made a HUGE difference in the way it pulls past the stock 5200 shift point to 6000. Shifts are MUCH firmer, yet not jarring, etc...

We all know results vary, but Hypertech got 35hp and 34tq with their 6.0.

Regardless, you'll love this thing because it's VERY easy to tune, and if you need to take your truck back in, you can put it back to stock in about 2 minutes.
