Hi, all, like title said , I'm experiencing some light surge with my stock cam Bolt-On Z06 at light throttle low load. I have lowered the timing in main spark table low load. I'm now at around 34- 35 degre between 1200 - 1800 . Great improvement. MAF are perfectly dialed ( pure maf only) I'm wondering if this have somethings to do with the EOIT normal RPM.
Why the stock LS7 have the EOIT drop like that at 848 RPM till 1920 RPM ???.
What would be happening if I'm put 32.5 till 2048 RPM ?
Should I will see some of this light surge improvement
Let me know,
I'm living with this light surge since I've improved the airflow of my car a couple years ago now. Headers, FAST 102/102, Vararam. ( I'm trying to figured out to tune this if possible )
