2015 yukon denali custom tune

[sixpointoh03]

Is anyone planning on tuning there 2015 denali. I had my 2012 tuned and got way better milage and ran way better. The guy who tuned my 2012 says that on the new one it records everytime it is re-flashed so your warranty will be voided.
Has anyone else done any research on this.

This is off topic but can you put ethanol in 6.2's ?
I know with ethanol engine produces more hp.

The new ones are not flex fuel the manual recommending that you run atleast 91 octane. I was hoping that e-85 could be ran in them since some gas stations in my area are starting to carry it.

all trucks record the tune even 07 up and they can void it. best option is to get a new computer from dealer and take your oem one out and just flash new unit.

I'll have mine on the dyno probably later this week depending on how things go. There are ways around the flash counter and CVN's

lt1z from my tbssowners.com forum has tuned 3 already. He has got 20-25 at the wheels more across the board on the dyno. Im looking forward to my escalade.

In line with what I've seen on the Vettes so that makes sense

How can I get around the flash counter

I'm going to to be leasing mine, so I won't be able to do a ecu tune right? Someone mentioned it above but how much would a new ecu be and swap it out?
