Hi I have been a member of the forum for a while and have had boosted cars in the past but never owned a car with an aftermarket superhcarger on it. What I have is a 93 Bronco with a Kenne Bell Twin Screw supercharger on it. I bought it off of an auction like a year ago and didn't get a chance to work on it up until a month ago. The car runs just fine but since it is off of an auction and I don't have any information about the history of the vehicle I don't know where to start. I am assuming that the ECU had been tuned so do I need to get it re-tuned? I noticed a small mechanical noise coming from the snout I am thinking to open it up to see if it is the spider that needs to be replaced. I am in San Diego,CA, do you guys know anyone or shop around here that can check out the engine/sc? Thanks very much in advance.
