CAMARO6 - View Single Post - ZLE engine laboring/stuttering under full throttle at track

IAT advance due to lack of coolant in SC loop will not do that, it will apply a fixed value to cut back timing based on MAT, it isn't that (see table below from 2017 stock ZL1)

It sounds like throttle plate is being modulated. Would need to see log to see if timing or throttle is being modulated. An HP Tuners log would easily figure this out if the correct values were captured. It could be fuel related but it is way to consistent rate wise and I assume this is a near stock or stock vehicle?

What mode are you in for TC/SC?
