Yes,But ,the ECU controls ignition firing or timing along with injector firing based on crank/cam sensor inputs so maybe you could modify or advance the sensor or trigger wheel. Tried this on a friends LHS chrysler for the hell of it and it wont even start,Scanner shows cam synch error and will not fire ignition. All depends on the program and tolerances I guess. Seems I read somewhere that advancing the cams on this engine disturbs the combustion efficiency or for lack of a better word,Factory engineered tuned runner volume that was a design characteristic of the Long intake and small ehxaust .Maybe someone with more technical knowledge could chime in !
