Hey guys, I seem to experiencing high LTFT on my 2018 mustang gt with gen 5 whipple stage 2 with kooks headers and high flow cats, Nguage and VCM scanner is reporting the long term trims are +20 at idle so running lean, car is running just fine under load and trims close in close to zero but they dont look great, not sure whats causing the lean condition, cant find any vac leaks or exhaust leaks so wondering its the tune. Any advice would be great. Gen 5 Whipple, Kooks Headers with Cats.hpt
