Hey yellow dog,
The snatchyness is more than acceptable atm. Because of the K&N airfilter it solved alot. Problem is the fact that the engine holds in at the range of 3000-4000 rpm and beyond 4000 the engine pulls again but not that hard. When I used the Dave V2 mapping (with standard exhaust and standard airfilter) this was not an issue. So with this new filter it gets more air, and I think the engine holds in at that RPM range because it doesn't get enough fuel (?). Does it make sense to think that way because with the standard pipe and filter, everything worked great, i replaced the filter (Dave V2 tune still in) and the pipe and it holds in.
I think I need to install some other tunes which have a righer F/A ratio from 2500 rpm (richer than Dave V2 and 20550).
Does anyone have some experience with tunes who can help me with this? (So many tunes,.....)
