Yes its the heat exchanger got the car up on ramps and belly pan off,just going with the PLM upgrade direct bolt in much better than stock.Its a highly modded car,its xblake old car mods are code3 pulley, inmotion can tune,needwings single,needwings ported manis,oil catch can.Now this is off topic but I respect any answer the car makes 348hp and 364tq at the wheels,why do car with the 61mm pulley make less or a hair more power,as bad as I want a 6imm pully it dont appear worth it.Xfireblake videos are on youtube and the video is proof,and I think the car is actually pushing 18lbs of boost,he did remove the gauge before selling the car,plus the car did a 7.88@90mph on street tires last month with a 1.8 60ft no brake torqing.
