shell V power

[gerrypassat]

been having the overboost problem,which came back after mr muscle (took about two month) somebody mentioned to me to try redex, anyway today put £20 of v power in and low and behold going up the same hill ,which normally results in overboosting and holding back , nothing just smooth power ,I`ve put some mineral two stroke in too ,but from now on will be using v power if anyone has any thoughts on this I`d like to know if the dreaded overboost comes back I`ll let you know
