Hes pretty damn good hes done some 93 Tunes for me and its crazy how quick the turbo spools with just a tune its awesome. I forgot to tell you guys i will be Full E85 not a 50/50 mix. I know,I know before you tell me i well not make the best power on Full E85 and better off doing a mix. Next year When i go bigger turbo(hopefully if the funds are there) I already be full e85.

 

wow e85 is only 2.93 here in MN. Need to know more about this tune and how it works.

 

sounds interesting, curious to see how that works for you

 

My 2010 SS didn't have a yellow gas cap. When was your build date? The SS shouldn't have an yellow cap at all. You'll lean out with a nontuned SS. E85 requires 30-40% more fuel, IIRC. If get you a tune for E85, then you can run E85. Unless you like detonation and fried ring lands, cracked pistons, etc. E85 is rated around 100-105 octane depending on the blend. With E85, you can run more boost/timing vs 93. I still haven't decided with my 01 L on what to run. For my 01, you need pumps for E85 but for C16 your fine. I will be doing a lower end build in the next year anyways. So, tuning is a ways a way for me. Unlike the SS, I have to wait to throw parts on my L. I have a dozen parts waiting to be installed. It really sucks... "Shakes fist at the LNF and Cobalt/HHR SS crowd"

Im not sure on the build date. I have the vin if someone wants to decode it.

But It does have a yellow cap.

 

The 2.0L Turbo from that year wasn't FlexFuel so not sure why you would have a yellow cap unless it was put on by mistake? Turbo motors generally can tolerate a higher concentration of E85 compared to NA engines because of their higher compression ratio. Using 100% E85 will more than likely cause problems though. I would look into it first.

 

Or...... Let the warranty take care of it when I approach 100k lol

 

If not tune for it I wouldn't put it in.

 

Have you been putting E85 in?

 

Negative.
