Agree with pauli. Altho i have no precise knowledge of the 950 if ur basics are in order then do some research to see if you need a programmer or reflash of ecm for running those mods. An injector being fired at a stock pulse width will also test good but the ecm would be firing it based on stock parameters. How is power and performance throughout the rest of your range? Is it only top end that seems lacking?
