I am getting a procharger this winter but will be getting the injectors and pump sooner so I can just get the tuner kit. What will happen if I just install the 39lb injectors now with no pump upgrade? Also do I need to change anything with my tune? The reason being is I can get a set of injectors but the guy wants me stock ones as trade.

Thanks!

 

You will need to tune it because the tuner has to recalibrate your MASS AIR METER for the INJECTORS.

 

^^^quick and thanks
