Which Octane Booster???????
 

I am currently awaiting delivery of a PROVA 'EIFEL' ECU for my V2 STI. I have been informed that it's been set-up for 98 ron fuel, if however it has'nt which octane booster would you recommend to use and what success have you guys had with these products??:wonder::wonder::thumb:

PS. I always run the car on Shell V Power or Tesco 99

never heard of that ecu, but NF Race is the OB to use IMHO - 60 ml per tank of V power ( better than tescos for resisting det)

Millers octane plus is good and easy to use (1 bottle = 1 tank) but your better off investing in something like a KS3 knock sensor (200+ quid) which gives you both a visible and audiable warning if your car dets.
