Well if you'r boosting high I suggest at least 91.. The car calls for it I would use it...Ive use 87 before but I was running 7psi...Your problem might be somewhere else.

I posted about it and everyone said NO NO NO. I had detonation and it was blamed on the 89. Well I found out today I had my base timing 10 degrees off. It runs without knock now, I will only be running 91,93 or e85 but for 5psi and under you should be ok.

Let's hope it runs better than you type.

Get better at it before posting here again.
