You took your airbox off, had basically just a open TB and had the car mapped that way just to ''simulate''?? Car fully mapped with no airbox on??
Sorry matey, i dont belive one word of it because it takes at least a hour plus to map specific (non generic), had mine done and it took roughly 5 hours!!, plus the large expense of it all.
No way would a normal member of the public go to all that trouble and expense. Yes take the airbox off and have it rolling roaded, but not to have it mapped that way when its off
Ok, right you are, I made it all up!
