my truck is not performing up to par
2005 silverado 2500HD 4x4 4door
no apparent issues but sucks gas like no tomorrow, lacking on performance also. My opinion, i've only owned the truck for 2 years and the performance has just never been what i want. any hardcore LS guys on here have any experience with proven packages
L92 heads/cam/exhaust/intake and dyno tune?
or build a turbo gig, how well would the turbo do while pulling a load for long periods of time
