stock the engine dont like above 6500 upm
-> i changed the fuel pressure up to 3,2 bar (~46,4 PSI)@no throttle ....
and 4 bar (~58 PSI)@throttle ... cause i think KL-ZE runs to lean over 6500 with stock MX-3 fuel system!
my APEXi RSM dyno shows me after this the maximum power with the stainless steel header, the metal cat and the 2,5" catback + this fuel pressure regulation
--> aprox 190 WHP @ 7050 rpm
and the engine runs fine with no shacking into the rev limiter @ 7800 rpm
thats a bit like honda
