A few issues with my Stillen supercharger

Bikeracer1098

Bought a 2016 370z Nismo which has had a stillen supercharger fitted along with the smaller 9lb pulley.
During the conversion which was done at around 1200miles, it also had the following Parts fitted - uprated fuel pump, fuel return system, ID 725cc injectors, UPrev GT MAFs, bypass valve, thermostatic oil cooler, ECUTek remap, Xtreme single puck clutch, gearbox oil cooler, diff oil cooler, cobra catback exhaust, japspeed decats, and uprated brakes.

Done around 1800miles in the last 6 weeks and whilst Car drives well, acceleration from 2000-3700RPM doesn’t feel as strong as the dyno graph suggests.



Recently the car has struggled to accelerate from around 2200 RPM during the first 4 miles and also the engine cut out twice whilst deaccelerating towards a junction.

Also on a few occasions whilst pulliing away from a cold start the revs rose to around 2500RPM

Car seems to run OK at the moment apart from not acccelerating as hard as I would expect from 2000-3700RPM

The company who installed the Parts and did the mapping are busy for the next 3 weeks.

Any suggestions? Could it be a faulty MAF etc

Thanks
