I got everything for an mpfi swap for my new daily driver 91 sedan with the D15b2. now Ive read a lot of articles that seem to contradict each other concerning what the swap does to mileage. this is my dd so I want it to get the best mileage possible. some say the mpfi gets better gas mileage some say swapping makes it get worse mileage due to the ecu being tuned for a bigger displacement engine and different cam etc. all comments and opinions on this matter would be appreciated

 

why are you double posting????

 

the mods moved this thread which made it a double post
