hey guys, the first time i flashed MHD was with the normal 91oct & it run great for a while before i began noticing the power dropping slightly after a number of pulls & a lot of timing corrections
in my country the fuel is poor & being a newbie to the tuning world, i figured the normal 91 is the one, but unfortunately it wasn't the case. it was running a bit poorly and i got worried.
i switched to acn91 to see whether it would be better. i had initially installed the tune with very old ignition coils & plugs, which affected the performance greatly. so i replaced them all & also got a vrsf catless downpipe fitted. the car feels much more alive. the downpipe gives it an aggressive exhaust note and even louder farts in gear changes
for now i am in stage 1 because of the high iat's, just to be safe.
i will be upgrading the Intercooler and Cold Air Intake, then jump into stage 2 / 2+
it is recommended to replace the ignition coils & spark plugs before tuning, install supporting modifications & also choosing the right fueling
all in all, MHD is awesome
