[QUOTE="tbsimmons, post: 1149710, member: 2026"] Well drove the truck about 150 miles yesterday. I usually had the Innovative Tow Tune loaded all the time with the stock turbos. That tune does not have enough off idle fuel. Once you are moving you are fine though. I switched to the Xtreme Street for the drive. Much better. Runs really cool too. Cruising at 65, I have 4.88 gears so remember my RPM is much higher than most, EGTs were in the 560-580 range. Boost was lower also than before which was a little odd to me. Taking off normal with stock turbos the Xtreme Street would put a pretty good puff of smoke. With these it is a lot less, they spool really quick. The other thing is that these turbos will peg the boost gauge quick. 59 and 73 Turbos are great in my opinion so far. I will post what I think of them towing when I go on days off is a couple of weeks. I am going to tow the fiver on the Street tune now just to get some more fuel off idle than the tow tune. This truck is a monster now. If anyone was debating on Turbos quit and do them. WOW. The No Limit Intake is really nice with these Turbos. Sounds great!!!! They do whistle a little out the exhaust. But really cant tell a difference in sound at idle. Driving you can, but mostly from the intake. Other than the intake sound the noise is not any louder in the cab. Power is really different. It honestly feels like the truck easily lost 2000#. [/QUOTE]
