Matt. yes you can tell with just normall driving, when i set off i can feel the extra TRQ in the low revs.
Gazza, tbh i never really felt any flat spots with mine before the map, but when i compared the graphs from both runs it has smoothed out some of the TRQ dip around the 2000-3000 RPM range. Also the map has not just increased the top end BHP/TRQ and has increased it right through the rev range.
E.G
Before the map at 3000 RPM BHP=73 TRQ=129
After the map at 3000 RPM BHP=79 TRQ=138
Before the map at 5000 RPM BHP=131 TRQ = 139
After the map at 5000 RPM BHP=149 TRQ=154
Max TRQ 159 lbs/ft@ 4250
The guy said i should see it release a few more BHP after it has been run in!
