So, I've been running this hemifever tune for a while, but I'm certain there is more in this truck that can be squeezed out with a full dyno tune..

Since my tune that Sean wrote for me, I have changed the gear ratio to 4.10s, added much lighter wheels and tires than the big ol 20s I had.. and I've put about 10,000 hard miles on it.

My appointment is for May 6th, and before that I will be re-doing the exhaust once again. I currently have headers into 2.5" per bank pipe that runs through 2 magnaflow highflow cats, from there it Ys into 3" borla XR-1 sportsman, which I love the sound of..

The cats are ruined now and I have a permanent catalyst efficiency code that I will have to get rid of before the tune. I suspect the tune had too much fueling on startup and that has caused the cats fail over time. So, I will be doing a new setup from the headers into a set of different style high flows that will fit in the space better, from there it will be a cross pipe into a true dual setup. I haven't decided on a set of mufflers to take the Borlas place yet...

This tune and exhaust will be the last love my truck sees aside from car washes for the next couple years unless I break something. I will keep you all posted
