Has anyone had any luck with resetting the speedo on larger tires? I have the u7193 in an 05 with 20" wheels and it seems to have raised the mph 5-6 miles higher than it should (seat of the pants) and 6-7 miles higher than a top end gps is recording (level road, constant throttle, high gps sample ...

I have the 5.3L with the Diablo runing the Volant with cold air ram. I couldn't tell much of a difference with the Volant before the Diablo 93 tune. The Volant, combined with the Magnaflows, and the Diablo seem to fit my needs nicely. I want to play some with the TM and other settings, but need a ...

I have mine for about a week now on an '05 with the 5.3L. I can tell you this, it now comes of the line like I never expected it to. I have 20" with the 3.23 and can break 'em loose off the line (not too far, but at least they yelp). What I like about the Diablo product is you can change many of the ...

I've not modified anything yet, other than the 93 tune, 20" wheels with 3.23 gears.

I've got Z85 kit, Volant cold air, ram tube, Magnaflow, and U7193 - That's it.

I got the USB cable kit, but can't use it yet - not supported

Numerous posts here indicate otherwise - no TM yet on late model GM

Mike,

I know you have had enough grief about the data logging and PC connect/download on the U7193, etc. and probably have no direct control over it. Wouldn't it be simpler to just post more clearly on your web site that it is currently not available and perhaps an ETA? I bought the U7778 kit ...

Okay...

5.3L Ext Cab, 2005, with Z85 Suspension, and 3.23 gears, running 275x55x20" shoes...Volant RAM, Magnaflows...

Just now installed the performance tune, and something strange happens, when I get on it, the rear wheels start spinning - both of them!!! This has never happened :P I didn't think ...

How did your tune on your 05 go?

I just got my 7193 in and am getting ready to load it up in the morning?

and, these procedures do not for the U7193, right?

Why do I still want this thing, but feel very misled ?

Now I am concerned, I thought it was teh U7194 that had not had the online and data capture feature as yet?

Are you saying, I can't do captures, etc with the USB and get updates yet?

I'm going be very disappointed if the Z-85 slug I have does not get a signficant boost (12-20 hp) in performance ...

It's the 2005, not very bright on my origiinal post - thanks Mike.

Based on what you said, I should be okay...now if UPS would get here...

Okay, I 'bit the bullet' and ordered my Diablo Predator - now having second thoughts about some of the details.

I have the Z-85 option on an ECSB with 5.3L and 3.23 gears with 20" tires, Magnaflow, Volant w/ Ram air. Not sure about the transmission - 4L60E probably (?). Truck is real sluggish ...
