Guys, Have any of you heard of mixing MS109 with 93 pump and the car running like crap? I have a 95 LT1 with a highly modded engine. I tried to mix 50/50 and took the car to the track and it ran like crap, bogged through first gear. It ran fine before I mixed the fuel. I have a tune for the 93 pump gas be didn't know if mixing the fuel would make it run like this.

 

Haven't heard of that specific problem. Did it clear up after you diluted it with your local 93 octane?

I'm closing your duplicate thread. We prefer that you post a topic in one forum only.

 

PLEASE do not post the same topic on multiple forums. It just causes confusion, and wasted time by the people who are trying to help you.
