GearboxZ 2007.5-2010 6.0L For Powerstroke +70 HP Competition Programmer GBZ-FED4

I have this tuner and delete on my 2008 f350 and i also did the straight pipe exhaust the difference is like night and day I went fron 13.5 gpm to 21 gpm and where my truck seemed like it had no power before now its a beast i straight up raced a couple of 1/2 ton street racing trucks and I smoked them I got it up to 138 mph. My throttle response is great its very very touchy

Works great can definitely tell a difference and was super easy to upload super quick shipping as well
