I just got my apr chip and I gotta say its awesome. On the aeb motor they dont have a 93 octance setting, only 91. So my question is will 93 octane do any dameage to a chip set for 91, Theres more pumps that carry 93 than 91 in my area. But if I have to switch I will go out of my way to find 91.

 

No damage will be done. If that were the case then you wouldn't be able to run Premium on a car that can run just fine on Regular.

 

Ok thanks. I called apr and got a lady from sales on the phone and said I should only put 91 octane. But I see your point

 

If your car is tuned for 91, running 93 will do nothing beneficial. Why do you want to run 93?

 

The only place I can find 91 is sunoco and there 91 is the price of 93 else were. But I guess I will stick to 91.

 

If you have to drive out of your way to get 91 then you are just wasting gas IMO.

 

Another question that i forgot to ask. Since im chipped should I swap my spark plugs and if so what kind should I get, or do i just have to recap them.

 

I want quarttro.

 

You should be gapped to 0.28 with your chip. NGK BK6REs are good plugs to go with.

 

all these questions could be answered with a quick search.... going up in grade will not hurt a thing, going down in grade will cause premature detonation and will pull timing... long story short you will waste gas

1 step colder than stock and .28..... i run copper plugs, i like them alot better than platinum or iridium plugs.... once i go bat i will possibly look into tri fire or something along those lines, but i think mike said he is running coppers.... but his car is a dedicated track car
