Yea I tested it again tonight in the driveway the rears would break lose got some tire spin and rubber smell but the throttle would then cut back after 4-5 seconds . With UPREV I couldn't do this at all! There's for sure more lowend with the ECUTEK . And not that I want to do brake stands but really with it didn't do this :/ Eh

Just purchased tonight and spoke with John. Looking forward to the experience. May have to start a thread of my own.

I cant believe you are getting 13.5x's 1/4 105 trap speed in your AWD.
i wonder if the gain comes from the first half of the 1/4 or the last half?

Is it a beast from the dig up to 70? Did you try DS mode?

I was shock to man! No I only used manual mod shifted at 7800 every time ( ex 2 ) the damn one I lost lol. Times were consistent !! 60fts were all 2.0's ,1/8's where all 8.8 or 8.7 and 1000 fts were 11.4's. The car was dead on every run. Now I just need gears :) .

Question: What exactly is different between the ECutek and uprev tune?

Fueling control should be comparable (if not, that'd be good to know), so the only variables I see room for greater control would be ignition advance or knock retard (ECUtek alleged greater control on the former), and VVEL -- not slamming ECutek at all here. Just wondering what it does differently to net such a large difference?

He John sent u a pm but still no reply

Differences that I can tell you,
Flex fuel,
Launch control, flat foot shifting, traction control just to name a few
No need for a boost controller, bc your gas pedals controls how much boost you want where with my uprev when boost comes on it comes on full blast, you don't get that throttle control like ecutek. The control is amazing.
But you can't tune your self.

EcuTek has a lot more stuff defined , awesome super high speed datalogging and loads more parameters and features.

What exactly do you want to know?

Who me?

Best way to get a response from me is via email.. this forums PM system is not the best - john@vtune.us

I had seen a new SRT8 Dodge Charger ran 13.3-13.5 sec 1/4 103 trap speed all day using a stick. Our G's 7 speed auto is very quick in shifting without loosing momentum.

yea there heavy too, The auto shifts well stock but tuned it shifts GOOD, the shifts literally were snapping, Was great, You can here the shifts quickness in the vids. Not twin disc ( Wish it was) but fast
