Let me give you a short version of a long story. If you have any questions after reading this please, post 'em up. I purchased my new 2010 R/T Classic Auto in May 2010 and being an "old MOPAR" guy and like 99% of everyone else on here, I wanted more power. Tuner, exhaust, cold air and long tube headers in that order. Not enough! After months of reading, researching, talking with others I bought a Edelbrock E-Force Supercharger. Had it installed by my mechanic at the Dodge dealership from which I purchased my ride. He did a superb job. Turned that little 5.7L into a BEAST, also turned it into a "BULL IN A CHINA SHOP"! Under WOT you could not wipe the smile from my face, however the other 99% of the time (normal driving) I was not a happy camper. Engine would be attempting to go under boost from every stop, lights, stop signs, going up hills and even while driving on cruise control, every little incline it would be trying to boost. Drove me crazy! Felt like the car was driving me instead of the other way around. I was very dissatisfied. In fact I started a thread here on CT and voiced my displeasure. That single post was my saving grace. Out of the blue came a reply to my thread......"I have a fix for that". Being retired Law Enforcement I was suspicious. My first question was "what will it cost me"? At this point I believe I would have stood on my head for a week if I thought it would have helped. His answer...."Not a penny, take it and try it". O.K. price is right. A few days later I received a "black box" with a couple of hose connections and a 12v connection. Could have been anything inside that box, maybe even a IED, but I thought what the heck. Simple to install, even I could do it. Placed a 12v red LED switch in the front cubby hole of console (where a small cell phone fits perfectly). WOW! with the switch in the "off" position my car drove just like stock again! No surging, nothing, just smooth solid power. Hit the switch to on and it was BALLS TO THE WALL again! UNBELIEVEABLE. That was two years ago. I have been over to Arrington several times for tuning, upgrades, dyno time, thousand of miles put on car and that little box has never let me down. (still don't know what's in it). Call it Supercharger on a switch, button controlled Supercharger or Supercharger on demand, whatever, IT JUST WORKS. Can't help but believe that it helps on the MPG especially while on the interstate, keeps all those little pesky boosts from coming on while under even the slighest load. Plus I like having control of the power, not it controlling me. Thinking about other locations for the control switch now maybe even on a steering wheel paddle control, that would be cool! Thanks Drag City for helping a total stranger. Your friendship and kindess will not be forgotten.
