Upgrades fuel pump Inline or replace stock

If you install the 2.55, I would have a free flowing exhaust headers back. Replace that stock 4x4 y pipe... That will help free up some ponies and cut down the heat.

 

Tor, the Wideband still stuck at 10 at WOT. I assumed that this was due to the FPR mod being mechanical 1:1 increase boost:FP overriding any tuning from the MapEcu. But based on what you're saying, I'd better take it to another shop and see if I can get a better tune.

Besides the pulley and shorties, truck has AFE CAI, MBRP catback, IPT VBU, and re-geared to 4.56

I also have 33" tires and some other heavy shit on the truck so it's a bit of a pig

 

Yeah these cats are really holding me back! I need to bribe my mechanic to not look under the truck when I go in for inspection Wish I was still in NJ where new vehicles have 5 year inspection grace period. PA is yearly which is just ridonkulous!
