I get a pinging sometimes at high RPM, since I can only get 91 octane, and the best octane to use in these cars is 93, I need an octane booster that works like it advertises, or need to get racing fuel and boost the octane that way. any recommendations? Thanks guys

You and I may be on the same adventure from different angles. Pursuing this from a water-meth perspective addition here.

Meth is cooler air and effective octane boost my friend. Doing the tuner search now then nirvana!

From a cost effective standpoint (one we hate to admit but does reign supreme) I'd proffer looking at a 91 octane tune. A lot cheaper and easier.

Yep. Swear by it. I research stuff till its dead, and i came to this conclusion. I run a fairly aggressive tune that requires fuel to be consistent. I use this to insure that it is, not necessarily to “gain” anything. Just to eliminate octane inconsistency in the fuel.

The octane boosters you see advertised that claim they raise the octane 5 points really mean .5 or octane goes from 91 to 91.5. the Torco octane booster is real but is very expensive for daily use. You need a quart to raise 91 to 96 on a 15 gallon fill. At $20 a quart that is mighty expensive.

If your car is stock there is no reason it should be knocking on 91, I would take it in and have the car looked at because something is wrong. If it is tuned you need to get back to the tuner and have it adjusted so it doesn't knock.

I've used Torco Accelerator for the entire time I've had my car (3 years) and the performance has been excellent.

When you say your getting knock how much are you getting per cylinder?

How would I measure knock per sensor? I'm guessing a good scan tool?
I'm not entirely sure its knocking, it only happens at WOT intermittently/sparsely and no other time.
