is the ppp designed to run on 95 or 98 ron fuel or doesn't it matter which ?. obviously it will run better on 98,

 

The PPP is designed to run to its full capacity on 97 ron fuel (and if you ever take your car to have or have been fitted with the PPP at Warwick they inform you to fill up at the local shell garage with sul )

95 will not harm it but you won't be seeing the full performance benefits.
