Hey guys. Im new to this website. I used to be on Bimmerforums.com but found alot of info different between euro and us spec cars.
I have owned an E46 328ise and an E92 335i and now im on an E36 328.
I swapped the manifold for the M50 about 4 days ago and i cant say i have really noticed a difference.. Yesterday i had to have another stab at it as i didnt realise the IAT sensor needed swapping out for the M52 sensor. I have now done this but last night i raced my friend with a standard 328i and we were running side by side to 120mph.. Is there a sort of 'learning' time the car has to go through before it really starts making use of the extra airflow or am i just after a remap?
