any of these vendors sites out there, id have to do some searching to find it, i'm sure the ngauge would work for you,
https://jannettyracing.com/collectio...ge-gm-vehicles but either way this is all your call, look around your area for some reputable dealers, when i did my headers and got the CEL i was like "might as well tune for e85 and got the flex fuel sensor kit as well. i've had 2 different tuners so far, the first just wasnn't doing anything right, i spent more time at the shop then i did driving the car.
Handheld tuner might cost from $400 up
