I've heard a number of people with the solenoid clicking problem, (from memory) some of who had custom tunes as well. Mine never had this with either standard flash or custom tune. For the 10PSI map: - You should make sure you are running the best 98 octane fuel available in your state. - Re-gap your plugs down to around .9 or a little less. The fact that some of the standard functions of the car have been effected tend to point toward an incorrect tune (for you car specifications) being loaded into the flasher. I would take it back to the place of purchase and ask to have the tunes reloaded into the flashbox. In the meantime, if everything works OK on the 8 PSI tune, then this will be OK to leave in the car. It's probably more linear in its power delivery anyway. Cheers
