14 gmc l83 tunes

So what is a good tuner to buy ? Out of the handhelds ? How many people have swapped intakes to the l86/lt1 with new tb and intake , did you notice a big gain on stock tune ?

You cant floor the truck after doung the l86 stuff without a tune.  and a handheld tuner wont do tbat. Youd  need an autocal and mail tune
