Hi all, just had se211s fitted to my 103, just wondering if l should use 98 or stick with 95 which is what is recommended for that motor. Cheers

I will call 91, the purist will say they will only use 98, I recon the guys that designed the motors would know best

Tune it on 95, will run on 91 if you go out woopwoop and that's all that's available, just go easy on the throttle, 98 for high compression, real high.

One mustn't get one's MON's and RON's mixed up.
