Duramax Hop up

[dicudmore]

What size are your tires and did you leave the catalytic on ? What does the the AFE cost and where to get?
Anyon else have a turbo backfire/cough when acclerating hard ? Usually on an uphill when temp is around 180, not quite warmed up all the way but drivin about 5 miles from starting? Right after shifting @ 45MPH then again @ shift around 60? Wont ever do it when temp is around 210 (normal)
that cough is typically an injector hanging up momentarily...
not all that uncommon on a low-mile truck...
happened on my 05 4 or 5 times , although once or twice it was at normal temp when it happened...
also, my MPG is up about 2 since adding the Juice module 16-17 over the weekend, 12-15 on prior trips

Dan now you need the predator so you can turn off the rev limiter..

i put a juice with attitude on an 03 7.3 PSD and man it made a difference, but on level 5 the EGTs went sky high if you stayed in it for any length of time. the truck has 4" exhaust but nothing done to the intake yet. another one of our customers has an 04 6.0 PSD with the edge box stacked with a bullydog box then an AFE stage 2, and 5" exhaust. its lifted with 37" tires and will roast them from a stop. i know that doesnt have anything to do with duramaxes, but no one drives the things around here????

Has anyone done the K & N intake? Good or bad?

Question.... what exhaust kits come with a catalytic converter?
I'm am all for ditching it but I don't want the tree huggers stringing me up by my nuts.
