I have been looking at the kits sold for Meth injection and they appear very simple. The only difference between the kits sold and the DIY systems is that the kits come with a box which activates the pump at a certain psi and tapers the pump rate as RPM increases, and the DIY kit relies on a pressure switch and turns on the pump as a constant pump rate from when it is turned on till redline. So, my point is who has ever actually build one of these kits and who has seen the difference between the control box and a pressure switch. Thanks.

Also if I build this kit I would not use a pressure switch, and instead use my EMS to activate the pump and solenoid at pressure, however it would work like the DIY kit in the case of the consistant pump rate.

 

I would be all for a DIY kit if i could have a some kind of fail safe....i would be worried that it wasnt spraying or i was low on meth or whatever......thats why im getting the buschur kit

 

Forgot to mention that a pressure sensor would be inline with the meth so if if there is no meth the ems would switch back to a regular map
