My truck is strictly drove on sunny weather or weekends only. Stays in the garage 90% of the time. Like I said my pump has been in good shape holds good rail so I basically know I can be at 600. Will I use the 600 tune? Probably not, it'll just be there to be there. Probably use a 500 or bit...
I'm keeping stock injectors/cp3. Not much larger than stock turbo. Shooting for 600hp but honestly if I thrash it around it will be on a lower tune than large tune (600)
So I've basically ran Interstates in my truck ever since I've had it, I like the warranty on them, but since I'm with a different direction with the truck; I'm looking for something for better performance and good price. I've been told Optimas but I'm just getting opinions, see what else is out...
So basically undo the bolts that hold down the upper radiator hose down onto the valve cover, undo thermostat cover bolts, lift cover up, remove old thermos, clean area, place in new ones, bolt everything back up, bingo?
