I have a 2004 Dodge 1500 4.7L 2x and just recently installed new tires and lift. Now it seems the speedometer is off and the truck is a bit under powered. What can I do to fix this. It is stock other than the 2.5" Daystar coil lift, Rnacho 9000XL shocks, and 285/70R17 tires. Is there a chip for this truck? I purchased a K&N Kit today and am waiting for shipping and plan to upgrade the exhaust but need an exhaust recomendation. Thanks.

 

try new gears to fix the biggest part of your power loss, then get a superchips prgramer, that will give a litle more power and correct your speedometer

 

do I have to get a supechips programmer specific to my truck? What is the approx cost? Can I install easily myself?

 

**** nevermind my bad. Superchips doesnt make a programmer for the 4.7, try hypertech? and yes the programmers are vehicle specific

 

ok nevermind on that too. I just checked their website, doesnt look like they make one either. I guess you'll have to stick with new gears and have the dealer re-calibrate your speedo

Which gears are you running now?

 

Gears, programmer (try Jet for the 4.7), maybe a CAI and exhaust. You can buy (superlift or something like that makes it, look at performanceproducts.com) a device that works in line from the sensor to the speedo to correct tire size changes.
