[QUOTE="jtpappy, post: 967307, member: 13967"] Well after lowering the 09 and going from 35" open countrys to 32" 420s and 5" above stock to 2" below stock I noticed that the way the truck drives is completely different...Going 70 the rpms are riding at 2K all the way, I am not sure if this is normal or not but on the 35s iirc its never use to ride that high to the point it starts crackling(exhaust). Its almost like I need another gear or something. The truck is a dd but a weekend street truck also so I am not sure if I can have the best of both worlds or not. On the mini maxi I have shift points set to medium and the tc locking in 4th and 5th. If anyone can give me some hints or things to try that would be very helpful. [/QUOTE]
