Modern ECU's don't have a replaceable chip, they have to be reflashed and you wont get 69 HP.
Your engine if you closely look is probably already being fed cold air so K&N wont give you 10 to 15 HP.
You have clearance for 285/45x18? Stock is only 225/55x18.
what is a "north start gam", a voltmeter?
did you disconnect the battery before replacing the solenoids?
did you check the battery terminal connections?
did you recheck the connections to the solenoids to see if you broke a wire?
did you scan for codes?
