I have a Hypertech Max Energy Programmer (part # 32004) that is Brand New. I bought it for my 09 Silverado but decided not to use it. It fits 05 - 10 Chevy and GMC with 4.8/5.3/6.0/6.2L. I would like to get $250 obo. I also have a K&N FIPK Air Intake System (part # 57-3050), it came off my 06 Silverado. It fits 05-07 Chevy, GMC and Cadillac with 4.8/5.3/6.0L. I would like to get $100 obo.
