Hi there!
I have a very strange problem!
I installed a Hypergear ATRG3 Turbo to my ER34 GTT, and from that moment the car stalls all the time..
Also went for a tune yesterday and the car was missfiring from 4000rpm till 6000rpm and then it knocks very HIGH
Like 116!!! That happened twice... So we stopped..
I have Apexi Power FC, Sard 800cc injectors, Sard FPR, Q45 Airflow, Stock elbow, 4" downpipe and back exhaust, 044 Bosch intank, OEM Coils(with electrical tape around them), HKS Iridium plugs(also changed them to Denso IK27), The car was working absolutely fine, before the turbo, injectors and Q45.
Akis.
