Sputtering @ WOT
Recently I went on a road trip, and my car was running fine the entire time. On the way back, I had to stop to get gas, and the station only had 87 octane. Given that my light was almost on and there was no other gas station for another 50+ miles, I decided to fill up like 2.5 gallons to get me to the next stop. I stayed off boost and drove the car easily unit I made it to the next station and filled up with 93.
Stayed off boost until I was like 10 min. from my house and when I hit WOT for the first time, my car started sputtering. And this entire week, every time I hit WOT, the car sputters. I have like 1/4 tank left of that mixed gas, still.
My question is whether you guys think that this mixed gas is what is causing me to sputter or do I have other issues? I haven't changed my plugs in a while, but I found it too coincidental for it to start happening when I mixed gas. Given that I am tuned, is my car extra sensitive to anything other than 93? Thanks in advance, and sorry for the long post.

run that gas out or preferably syphon it out to prevent any risks of det unless you have a way to log your car and see. then fill it up with 93 and check your plugs. i would also go ahead and do a boost leak test while your at it.
it could very well be a combonation of the 87 and maybe it was a bad batch of 87 at that.

Ran the last tank empty and filled with more 93. Still sputtering. Gonna try plugs now. With the power that I am making, should I run a step colder or am I fine with stock plugs?

I've always wondered how the car would act if I let my fiancé put 87 in it....she will be reading this in the morning. Maybe now she'll understand why 93 is very important.
