my truck is still pretty close to stock, and im tired of being out-towed by my brother in laws duramax (its an 03 LB7). i'm thinkin a 100 fuel plate, and either a 3 or 4k gsk?(with 60# valve springs) and a bhaf. 4" DP and 5" exhaust are goin on next week. which gsk should i go with, and will this be enough to atleast keep up with him loaded?

 

the 100 fuel plate will do nice and from what i heard that is lil purpose for a 3 gsk because you will soon want to upgrade to a 4gsk

 

X2 on the 100 plate, it will make ur truck feel like a new one. i bought a #10 plate and it did pretty good so for s h it s and giggles i ground my stock plate to a 100 and all i can say is wow. never ran a duraturd loaded but i can take my buddies 04 dodge loaded and hes only 1000 pds heavier than i am. just watch ur pyro on big grades when u got er to the rug
