Racechip Ultimate Tune Piggyback (N63TU) 650i 550i X5 V8
Had it since July, but switched to a DME tune last week. Per Racechip, this will give you 22% more HP and 23% more torque (549 hp & 590 lb/ft) the boost levels are adjustable via a dial. Includes bypass harness, which allows you to go to stock within seconds. Tune is off the car and ready to ship! Last edited by AmooManiak; 02-23-2018 at 07:56 PM.. |
