Ok thanks for clearing that up for me. Just trying to weigh all my options with the bbtune. Sorry to hijack your thread. BTT.
Bro, talk to Justin before hand. I'm a little confused here because I ended up going with the 87 tune. I believe the guy that was helping Justin the day of my tune was Alex. I told him I usually filled up with 87 but switched to 93 for the tune and explained to him how I was told I could do the 93 tune but use 87 on occasion with no pinging, but if i did the 87 tune and used 93 I would have pinging. Alex told me it would be better to do the 87 tune and I could use 93 for more power etc from time to time with no pinging. If i did the 93 tune and used 87 i would have pinging.
I told that to Justin while doing the ride and he said he would do the 87 tune and make it so that I could use 93 for added power etc. Now this is what I was told by Alex/Justin. I haven't used 93 since the tune, i have more power and get up and go with 87 than I did before the tune. I will use 93 on my next tank or so and see how much of a difference i feel. But I would at the very least confirm this with Justin or Jenna before your tune.
