Yeah, I think that does sound more efficient/better/less prone to failure due to clogging etc.
Back to the PWM controller, I tried it out last night and... well there was a fairly violent electrical explosion, the biggest one I've seen from a simple 12V circuit anyway.
So, I need to get a replacement mosfet and check what the heck I soldered in wrong. Powering the EGR valve up manually it doens't pull more than 1.3A, so the controller is plenty capable of handling the power requirements. I must have done something wrong at assembly.
