X3, no need to ever put a set of laser cuts in your truck. Theres no need for excessive smoke and alot more heat. Like 94 said save up for some better injectors

X4.........

IMO...Full cuts have no place on the street,power can be made without their use.

I agree I loved my 191's for the street

Give chris a call @ SDX for a great set of injectors at a sweet price

Yes...
IF you were keeping a log of what changes you make or made the day you dyno so you know what or how you had everything set up to fall back on.I keep a log book on mine and have since day 1 and can show you everychange I made and what worked that day and what didn't.I learned that when I was racing my superstocker as it helped to dial the car at diffeent tracks and helped when you needed a hundreth or two in a heads-up class race.

The tune with full cuts will be alot different on the dyno than the 191's as they will overfuel down low and could put the fire out killing your attempt at any big HP number.Thus the reason for logging what you do so you have a way to fall back and get yourself close for the show that day......Andy
