Having issues where the car is losing power over 7500rpm.

Dyno says up on power low and mid range and drops off after 7500rpm

Possible loss of 10-20bhp over same spec cars

202bhp on the dyno

Standard ECU

On track seeing temperatures of 100-115 peak degrees Celsius.
and noticeable loss in power straight line compared to other Series cars. maybe 5-10mph down on the straights.

Anyone think of any issues and things to check, change etc.

Trackday videos showing a noticeable change between a couple of days in top speed on the same track. Cant recall changing anything other than fresh plugs same make.
