hey guys. got my 2001 e46 320d (136bhp model) remaped today. can't say i was to impressed :(
on the first dyno it read 123.5 bhp so im down there already! we unplugged the MAF sensor and it went down to 83bhp just as it should just to check that was ok.
after the remap it got to 145bhp.........thats pretty poor and the torque was only increased by 40nm. the guy who did the remap said there could be an underlieing problem as to why it is underperforming. the MAP and the MAF sensors are both ok as i have checked them and cleaned them along with the EGR valve.
are there any other componants i can clean check or replace that could make it underperform?
