Done! Thanks Mike.

When I last spoke to him about this issue two weeks ago, he said that he had contacted Diablo but that a resolution was not offered. What should I do?

Mike,
I need help with the trans tune on my ATS. Currently running the hard Diablo trans tune. Is TM totally disabled by default with this tune or do I need to manually disable it? It feels like it's interfering currently by fluctuating the throttle. Today it was 31deg F and the motor was running ...

Bad news racing makes an amazing tune for the ATS 2.0T and any other LTG. He can send you a CMR file. I noticed a big difference in driveability over the canned tune.

So does this mean that the importance of the fuel trim number is no longer a factor in adjusting the tune? If it is, can and should that value be adjusted via CMR and to what benefit? I'm just looking to ensure that it's not running too rich or lean.

Thanks

I've recently switched over from running the 93 tune to the 91 tune and am really surprised in how much better the 91 feels.

Mike or DiabLew,

Installing the TRS catch can tomorrow. I'll be cleaning the factory intake tube out and removing the white plastic silencer / restrictor. Will this cause the AFR to get too lean or have little to no effect?

Using Shell 93. I'm a bit skeptical of the local Exxon gas after seeing a lot of knk on my old car. I know a few people in the area running big boosted cars around here that only use Shell and have zero issues.
Per your suggestion, I will try it again.

Hi,
I've got a 2013 ATS 2.0t with 22,000 on the clock. I've logged the stock map, 91 and the 93 tune. I'm seeing what I think is way too much knock retard going on with all the maps but the car seems to be driving just fine and with the tunes, WAY more than fine!
Running Shell 93 here in Georgia.
No ...
