Having problems with a Roush TVS cal on a 15 5.0 GT. it won't achieve WOT commanded lambda and has some unusual spikes up to 4500 rpm. Above that it's fine. Turned off cyl anticipation and maxed out both mulitpliers. It has long tubes and I have worked with the transport delay and time constant with no effect. turned trans and clutch protection to no avail. I do have a datalog, but it's in LiveLink Gen 2 configuration. I will attach it, the car is tuned with HPtuners and I can attach the file if needed. I installed the Roush cal, then pulled it out with HPTuners and modified it from there. Roush won't send a cal modified for longtubes. GREGSCHUBERTTVS-3WOT.csv
