Vacuum tool for your Q50-Q60's heat exchanger. I recheck my BMS and the cooling system.

Double checking my 2019 tuned Q50 3.0T's heat exchanger for air bubbles or obstruction. My Burger Motorsports assisted heat exchanger system can run upwards of 130 to 140 degrees on the seriously hot days and gets heat soaked, fights cooling back down until I can hit a good 60mph stretch of road. My car still runs good and pulls even while 130-140 CAT and CACT of 120ish. Limp mode likely 160 degrees and above while continuing to driving hard. I've had my HX pump turned up to the constant 80% in the Ecutek software. Next thing to try is to have the fans come on sooner like when temps climb over 210 degrees. All done in the Ecutek software by the tuner.
