I do. I have also started to think that the 22' wheels are made out of lead too. They are so damn heavy. I' guess I'll go back to grandma driving for a while until I sneak up to an unsuspecting ford in motion..CANUCKPREDATOR wrote:DUDE you must have a lead foot!!! I have a 4" lift, 305/55/20s and I get 16-17 on the highway, 12-14 in town. I get 10 MPG with the trailer and ATV on. I guess racing Fords is expensive.
sickREDsierra: I'm glad that you have enjoyed the thread. I'll keep you guys posted with any other races hopefully not so shameful as this one...By the way, the other day I barely beat a Jimmy hahah...but oh well, thats another story.
I have read on several forums and there appears to be some people that claim that their 4.8 runs like a raped monkey with a custom tune. Could I benefit from one? Where can I turn ON the Raped Monkey option on the predator???

Performance Mods:
-Predator Performace tune with 93 Octane Gas
-K&N Cold Air Intake
-Magnaflow Stage 2 Single Out Exhaust
Johan, Sounds like a new tune name. Johan makes an RKL tune for the Dodge diesel predators for Road Kill Larry. This would be the RP Tune for Raped Monkey Tune for the GM Gas Predators...something to think about.Chevy_Power_06 wrote:I do.

I thought mine was decently quick, I expected less than 16 second flat quarter time, but it didn't happen. Most of it's due to being a slug out of the hole. They pull pretty good for a truck if your moving and make the trans shift down into 1st, even for the small 4.8. The new 4.8's make more power than the early 5.3's did. Then again the 5.3 has received the same upgrades, so they still have the same gap in horsepower and torque over the 4.8.I have read on several forums and there appears to be some people that claim that their 4.8 runs like a raped monkey with a custom tune.
