I HAVE RECENTLY PURCHASED AN X3 TUNER FOR MY TURBO TERRITORY. I HAVE ALREADY DEBUNGED EXHAUST AND FITTED TYPHOON INTAKE WITH K&N AIRFILTER. I LOADED 10 PSI BOOST GENERIC PROGRAM. THE PROBLEM IS THIS, WHEN I FLOOR IT IT SEEMS TO SURGE AS IF IT BUILDING BOOST ON AND OFF , WHAT DOES THIS ALL MEAN ????

Your problem will be that your using a generic tune. Do yourself a favour and get it custom tune so you know it is running right for what the car has in it. You cant tell someone I have this car and these mods and get a tune email (or whatever) to you, it just doesnt work. Each car reacts differently to what you put on it so that's why you need it custom tuned.

Your boost solenoid could be sticking. Or generic tune could be program with the wrong spring rate for the actuator.

Its just the 10psi tune, Try the 8psi tune till you book in for a custom tune.

try gapping your plugs also

I would have just read a couple of the million posts on here about this GENERIC tune and not took the sellers word as gospel. Expensive car your dealing with here spend the money and get a custom tune!
