So i was wondering if anyone is running any kind of tuner on their new 16 plug 4.7 i just got a smokin deal on one for a work truck the engine out the box is a dog so i was thinkn 4.10s and a tuner would wake it up and all the chip companies say 40 hp to the wheels that sounds alil crazy anyone have one to vouch for that ??
50hp and 55lb ft MAX gain for the superchips. Hypertech's dyno showed similar results, and I assume diablo would be similar as well. The peak gain is roughly 15hp and 30lb ft gain. Definitely a noticeable difference, I won't drive mine stock anymore. Between the tuner and 4.10's the truck would be pretty quick, faster than the 1st gen hemi's(stock). The 4.7L makes good mid to high rpm power it's the low end that is lacking, the gearing would help with that. I plan on getting 4.10's as well...2,500-3,000 rpm is where the torque comes on, I've actually had mine break the tires once it hit 3,000 rpm, but won't do it from a stand still(unless I power brake). My quad cab 4.7L with superchips, 3.55's(open), and airaid drop in and MIT does a quicker 0-60 than my friends 1st gen quad cab hemi(stock) with 3.92 LSD did.
With the superchips you'd be looking at about 325hp and 360lb ft, with an intake and exhaust that's roughly the same as the old hemi.
