i have a friend w/an 03 duramax crew cab. i have spanked him numerous times and he races mustangs on his weekends so i know he knows how to drive. and all i've done is whats in my sig.

how much of a differnce do you think the rear ends will make? I dont know what his is.

i never considered that point. i have 4.10's in mine and when i've raced him, i get him off the line and keep the same distance ahead of him til about 60, then i let off. he still isn't catching me when i let off, but i've driven his truck before and it doesnt seem as quick as mine, but at higher speds (above about 50) his seems to pull pretty strong. i have also towed my trailer with both trucks and mine seems to have much more power when towing.

hey guys look at sig and i will tell you i drove a dmax with and without the juice without it she runs ok with it i would put money down agaisnt a mustang that thing pinned me to the seat. but now we are bigger than this we can go faster just costs more. but we have the best engine proven record just my 2 cents
