I've got a late build 04 cclb with ********** tunes, snow stage 2, studded, ******d, mbrp 4 inch single smoker system, volant intake and found i have lifted the heads again. Truck is getting arp625 studs and o ringed. Shop i get my performace stuff through is trying to sway me to a non vgt turbo. Truck is my daily driver and tows approximately 15k about once a month. Injector upgrades are also a toss up. Thinking 175/30 or 190/30 as i like to play with it too. Shop is recommending s364.5. Anyone run this as a daily driver with either set of injectors? My worry is spool up time on the fixed turbo. If i go with a vgt it'll be a kc stage 2 as i have driven a truck with stock injectors and this turbo and was rather impressed. Thanks.
