swap the flowmaster for a straight thru design muffler, swap that bullydog for a custom tune, get rid of that throttlebody spacer. The intake is fine. Get some long tube headers, lower gears, higher stall tq converter. Those mods along with the custom tune will have that 6.0 moving out.

You literally did the worse possible mods to your vehicle, you want more performance? Return it to stock! You want the best bang for your buck, get a higher stall converter. I had a 2800rpm converter in my truck and it drove completely different. Also you might want to ditch the factory dual exhaust and get a single 3" exhaust set up.

I dont think returning my truck to stock is going to get me more performance HAHAHA! maybe less tho... but im sure a higher stall torque converter would help a litttle. What rpm converter should i get ya think?

Yea that was a bit of sarcasm, picking a converter is tough work man. I searched for months before I decided to go with my 2800rpm RevMax converter. Really all your mods and driving style all need to be considered in picking the stall.

a set of headers and a custom tune is the next step. If you really want power find a sc set up for it that will give you a huge boost in power.

get rid of the tb spacer, doesnt work for our trucks only tbi engines, also long tube headers, black bear tune (a must), electric fan swap, single 3" exhaust with a short magnaflow and think about maybe a shift kit for the tranny along with 2800-3200 stall
