At 16psi as it reaches the 6200-6300rpm, the car slows down, rpm falls down to 5000,
and the pressute too. It exists until I step off the gaspedal.
If the pressure is higher, this symptom appears sooner:
18psi-> 6000rpm
20psi-> 5500rpm
Why does it happen?
What can I do, because i wanna use my car on 20psi?
spec:
1.6 low comp Mahle
superchips(unlimited boost)
FMIC
denso racing fuel pump
305ccm injectors
champion QC59C
T3 stage3
thanks for your help

If its boost cut you should feel it quite violently stop, usually a loud back fire and the rev counter will drop to 0 and then resume........and will repeat that process until you back off/reduce the boost
