Hello all,
After porting work, the performance of my car drops except in the low 2200 rpm or lower. Above that mark, torque dan hp drops. In fact, in the rpm 4500-5000, they drop significantly (proved by dyno tests)
No other mods I use except the knn air filter panel.
If it is because of the porting, as I suspect, can you all help tell me the causes of the drops? Tx.
