If this is a self learning system, you will never get it to work starting off at 9200 feet if you foul the plugs in 6 miles-----------


You could take the car to a lower altitude and start there , let it learn, and then drive it progressively back to the higher levels--maybe-----------


The highest pressure that the map will read will be the baro at 9200ft----------and it that reading it will flood the engine with the duty cycle injectors he probably has-----MAP does not compare anything to any thing--it is the ABSOLUTE pressure in the intake manifold where the sensor is located----------it will (on an NA engine) it will always be equal or less than baro at that altitude, never more (unless supercharged)------------


And on many builds/tuning deals that I have been involved wit, it has been almost a consistant occurrence that many basic auto things have had one or several discreps that violate the tuning process==== exhaust/vacume leaks, temp sensors mounted (or completely missing) Teflon tape, poor grounds----------this fouling plugs in 6 miles 10 minutes-------SHOUTS out the likely hood of more than one, possibly several ----------
