My motorhome is a Transit 04 2.4 TDCI with 125ps i noted that EVO CHIPS (in which we are a dealer) quotes 30bhp more and 20% better fuel economy will this in anyway waer the engine at all, as it has to be as reliable as can be, its only done 13500 miles but dont want premature wear, i see it will put out nearly 155ps

Whats your thoughts guys & gals?
