"all the extra power"... :rofl: remember this is a 1990 Accord
I have decided to run a little advanced. The throttle response is so much better. Retarded the car felt so sluggish... gets good enough mileage anyway. I usually get over 30mpg with mixed driving. I'm currently running 17BTDC ignition timing on 87 octane. Pending any pinging I will leave it at that, feels good...
