Anyone here have a 2008 GMC XL that can shine some light on whether the upgrades were worth it.

I installed the vararam tri power on my fathers denali (6.2) and it made a huge power gain with a little tweaking from HPTuners.No dyno numbers but its faster...lol he can keep me in sight a little longer now!
