Wasn't perfectly happy with my map after running the Kev fuel map for the last couple of weeks.

         So thought i'd try a different map to see if i could make it a bit better as i was getting a bit of throttle hesitation at times.

         Went for the above which is the M412-518.djm from the list on here. Felt a lot better and seems to have smoothed it out a lot. Possibly becuase i'm still running the Baffle/DB killers in my CCC cans and this map probably fits more of my criteria that Kevs above.
         
        
 Should really check my ECU and see what version i have on my 06 plate really just in case i go for another.
         
        
 Just for info i have an 06 XTX with CCC stubby cans, baffles in, PC3, Stage and stage 2, snorkel removed, AIS blocked up.
         
        
 About to rain here so never got many miles in on the test, but enough to be a bit happier.
