4th gear pull

3rd gear pulls I’m installing a csf heat exchanger to have the car’s temperature a little more minimize it should have no affect tuning correct?

3rd gear

BMW f30 335 e50 with MHD Stage 2+ tune Mods: Pure Turbo Stage 2 turbo (ps2), High flow Catted Downpipe, MZD flash, vsrf intercooler, fuel-it stage 2 lpfp, dorch stage 2 hpfp, turbo blanket, vsrf exhaust, cold air intake

3rd gear pull I’m not using full throttle. Drive train malfunction kicks in around 4.5 k to 5.5 k rpms. Killing all power and torque.
