I already searched. I didn't see any thread on what sparkplugs should look like on e85.

 

That's a good question. I haven't checked mine since I went e85 back in Feb. I'm going to check this week and l'll report what I find

 

are you pulling the plugs out after idle?

 

Mine look normal. If they're white it means you are running lean I believe. Who tuned the car after the switch?

 

Here are my plugs. Just pulled them off. They're greyish. Car idles smooth and no breaking up at any point in the powerband. These plugs were installed back in Feb when I first converted to E85. Haven't been off the car until now.

 

How do you not eat plugs. I usually got 2-3 oil changes out of a set of plugs on E85. I just upgraded to a COP but I'm having similar off boost (and sometimes on boost) acceleration hesitation. I'm going to order some more spark plugs.
