Hello everyone, I have a question for those in so cal or even everywhere else, I just tuned at rre made 415hp 397tq on e85, I already filled up about twice since I dynoed, and was wondering how many of you fellow evo owners test the fuel before you fill up. I know there's the guage from zientronic that's available, but kinda pricey. I purchased the tester from stm website, and was just wondering how many ppl test the e85 or if they even feel its needed to. Please excuse me if this is in the wrong section. Thank u

 

I would recommend testing your fuel if you go to a different station, I would just recommend using the same place you filled up at before the tune.
