hey im new to the site. i have a 03 dsg lightning. my current mods are K&N cai, diablo programmer, bbk twin 65mm throttle body, and silver knight mufflers with 2 rear cats removed. my best current 1/4 mile is 13.47 at 102.7mph. i would like to get my e/t down more. my truck currently has 80xxx kms but had 36xxx 3 years ago when i bought it. i was wondering if it is safe to run a 6lb lower pulley and a small shot of nitrous. oh i also have m/t drag radials. ive put about 25 passes in the 1/4mile since ive bought it. but i want to up the hp since my cousins srt-4 is pretty equal to me on a roll. until we hit more top end. any input is greatly appreciated. cheers!
