I've got some low speed surge on a mildly cam'd LS1 (M6 - manual).
I've rear several thread and understand how the TC & TF might help with this.
However I've logged the IAC_TC_DMA & IAC_TF_DMA on both a 1221256 & COS5 OS the TC PID is showing basically zero adjustments. The TF is adding air to match any changes I make to tables.
As I don't have a CPP switch or the wiring as I'm using a Holden based wiring loom & PCM. Maybe an automatic OS might get the TC tables working again?
Any other suggestions would be appreciated.
