sensor enhancement help?!?!
 

I am very close to installing my HHO system on my 2006 4.7 V8 Dodge Dakota, , I am now at the sensor enhancement phase. I need a MAP and Dual EFIE enhancer. I would like some feedback on which digital MAP/EFIE enhancer I should go with while trying to avoid paying an overly ridiculous price. Is "soft start" the way to go, and what about a digital voltage meter?
Any Ideas?
