performance chip advice
im hearing mixed opinions about performance chips, can anyone break down for me if a chip will be good or bad for my truck? i have a 2007 silverado Z71 classic body style. i dont want any long term effect on my transmission or drivetrain but i would like some better gas mileage and if i can get more HP/torque at the same time that would be great
they just seem to good to be true i've heard horror stories and dreams come true

about 90% of the guys on here will suggest doing a blackbear tune. its about the same if not less then a chip. check out blackbeartune.com i think. good luck. if it seems to good to be true then its probably not worth it.
