RCZ 200 with slight acceleration flat spot

otherwise all is good - great performance, incredible economy - what causes this flat spot and what is suggested inexpensive cure

First thing are you using premium fuel? It’s a must, then your looking at plugs and coils.
Air filter standard or high flow?

recently serviced and standard air filter - fuel variable

Hi I had one on my 200 GT so I changed the air filter for a fast flow & cleaned the Mass Airflow sensor on the intake side & Changed the Map sensor on the intercooler side & mine appears to have disappeared but flat spots are a pain to detect & a vicious circle as you may have a failing coil pack or packs or even the plugs are saying cheerio maybe try a code read to see if its picking up a fault
good luck

I dunno if its the same but when my car was stock there was a flat spot mid range where to torque peaked then towards end of rev range it would pull more as the hp peaked.

After a remap no flatspot the pull from low down was crazy all the way to redline, 275nm to 360nm huge difference in torque

Let us know what size remap did you install I'm considering going up to 230 bhp to get rid of the fuel drinking lower range "drag" that plagues the 200 GTs

The map I had claimed 220 and 360 got it dynod and made exactly That, honestly made the car feel perfect i felt it was lacking torque before but after the map it was even quicker and surprised some cars on the road
