Well, the BB tune is installed and I have some comparisons...

Bottom line is I have to give Diablo credit as they do have a good product that does make a difference, but the Black Bear tune does go above and beyond. I'd say I have atleast 30K miles on a Diablo between my old 6.0 VMAX and 6.2 for ...

Unit sold and shipped.

PM sent with info..

I want to get a Black Bear tune. But I have to admit... I had an offer and sold it I thougt, but then the buyer didn't put money in my paypal or send me a shipping address... So now I have driven 2 days and about 200 miles back in stock form.... I lost 2.4 mpg and the throttle response is terrible ...

TTT - $200 - Its boxed and ready to ship....

Used on my 2010 6.2. Have original box, computer cable and power supply. Unlocked. $250.00.

Thanks. I checked everything and could not locate any type of leak. I'm not sure how I could even bring it in for the dealer to check out as they would wonder how I learned of the fuel trim varience. The truck has about 8500 miles on it now and it has stayed the same since I installed the tune at ...

To reword it: My slope is at -2 at I have -.56 left bank and -5.78 right bank.... Any long term issues...... And yes, it runs very hard at WOT! Ican't complain!

Hey Mike, Just looking for your opinion on running 0 and -5 for trim.... Actually, what impact does running greater than a fuel trim average of -2 hurt... Its not like I can bring my new truck in for warranty work and state the fuel tirm is not right so there must be a problem...

Thanks.

Not sure on an exhaust leak. There is no sound or indication of one. Fuel tirm stock (new) with 250 miles or less when checked last March were that much apart... Is there any concern or just run it so it averages between 0 and -2?

Well, I have to give you credit on the shifting improvement.... On ...

I just updated to the new version from the version 15. In both cases I have noticed up to 5 percent difference in fuel trim numbers from left to right. I'm now at plus 1 and neg 4 with the slope at -2. Is this common to have that much difference between ...

I just updated to this 9T18C version and had been running 9T15B for about 8000 miles. I've only put on about 50 miles so far but really haven't noticed any difference.... Is there going to be much from that version?

Also have had a constant problem with fuel trim being 5% different between banks ...

Guess its tome to try a Blackbear tune.
