Just got a new ecu and injectors

[Allen1245]

My car had the misfire code on it now that i have it back it's not the same anymore it seems to be slugish and the vvtil is kicking like at 6200 rpm. Which is strange because my other ecu was at 6k so anyone know whats going on?

Your factory tach is not accurate enuff, so that 200RPM difference is normal. Lots of pple have had that question for when lift kicks in, and the answer is the average between 6k and 6.2k
