Spend the extra and get the better gas. It costs about 2 bucks more per tank. Once you get everything dialed in, you'll still be saving money because of the increase in MPG.

I haven't adjusted my LTFT yet as it is still cold out, and I want to wait for warm weather so it doesn't run lean in the summer. I have the L33 HO 5.3, if that makes a difference to you.

UHHHH...I think you run leaner in winter since air is colder and more dense and richer in summer when air is ...

I've got a Cherry Bomb Extreme single chamber single in dual out with Magnaflow stainless tips on my 05. I have 160.00 in the whole thing. It's got a nice rumble at idle, but it rivals straight pipes at WOT. I have videos if you want them.

I have my shift points set by RPM(WOT). My 1-2 is 5700, and 2-3 is 5600. As far as line pressure: Part Throttle=1-2 is +1 psi and -2 seconds shift time, 2-3 is +2, 3-4=+1 WOT 1-2, and 2-3 are both +2. I haven't adjusted my LTFT yet as it is still cold out, and I want to wait for warm weather so it ...

This is just a prob with the U7194 right?. I have a 7193 on a 2005 GMC with the B code motor and have been running 9r06 for a few months. Do I need to redownload 9r05 to my Predator, and then the truck?

I've got exhaust, I just need a CAI.

OK. I've run my tune for about 3 weeks now. I am very happy. I know my 3.42's are killing me(32 inch tall tires), but once I'm rolling, it's an animal. I can't wait to get time to datalog, and get my LTFT's dialed in. I also noticed about 1 MPG better mileage. The truck caught me offguard the other ...

I did the Diablo tune. So the fans running more is normal? If so, I'm not worried.

I do have a question now. It seems like my fans are running more now. Does anyone know the factory on/off settings so I can readjust them?

Got it today. Loaded the 93 octane tune and tweaked the shifts point and top speed a little. After a week or so I'm going to datalog, and go into DSLogredux and see what it says. I can tell already it pulls hard through 1st gear(upped the shift point to 5700) I can't wait until it learns the tune ...

Great thanks.

I'm going to order this week from Maryland speed. Since the newest revision or the 7193 came out back in the summer they should have it, right? I want to make sure it has the datalog capability since that was one of the upgrades.

Buy it. My truck is a beast with a (slightly modded) Diablo tune. Make sure you get the PC interface kit. I believe Maryland Speed (Google) actually throws the kit in with every Predator purchase --- other vendors may as well.

A. check

B. Slightly more. Expect 0.5 to 1 mpg improvement (if you can ...

I'm getting ready to purchase a Predator in the nest 30 days and I was wondering what kind of gains I can expect. I have a 2005 GMC ECSB Z71 with the L33 aluminum 5.3. I plan on running the 93 octane tune, and I buy my gas at BP stations(recommended by Diablosport). I'm looking for
A.More power
B ...
