Supercharger Starting/Idle problem

hyunsoo1803

The car now has 70,000KM and that Stillen Sc kit may be stressing the engine with old spark plugs. My car is going to for a tune check up sometime this week.

I have some questions for experts in this community

1. Spark Plugs: What system, or brand do you guys use for FI application? Anything one step colder than OEM ones?

2. What's the a/f ratio range when the idle is unstable. For me, it was 13.5-15.2 surging up and down while RPM needle struggled to keep the car running. When stable idle, it usually sits at 14.4-14.7

3. Do you think SRM affects the idle RPM speed? I remember my tuner saying he set the RPM to 800 to 850 ish but I sometimes see stable 700-750 :/

VERY CONFUSED
