what plugs should I be running?
Here is my setup
HKE 408/ AFR 205's,ARH 1 7/8 w/Catted Y,Fast 92&NWTB,K&N FIPK,HS Modified rockers,Pwerbond UDP. 11.2:1 CR tuned for the street on 93 octane.
circle D 4l80e and Circle D 3C converter.
konis,Adj PHB, 1Le Front S-Bar. MWFab9 3"short,Tunnel mount TA,MW LCA,Wavetrack w/4.10 gears,3.5"PST alum DS.
Billet Specialties 17x11 4.75 bs,17x7 fronts.
Best 11.2@120 1.56 60'
Im having a hell of a time tunning the cars Idle. It surges like crazy. I have tried everything I can think of with no luck.
I need to change the plugs bc its running too rich and I think they are fouled.
it was registering anywhere from 10-11.5 AFR

With HPT,
>Engine
>fuel control (This is the area you need to modify.)
>general Fuel (aftersart enrichement) {Take a look at the tables}
Also check Accel enrichement (not for idle though)

NGK TR6 would be a great plug for your setup.
The next step colder plug is a BR7EF and it may be a bit too cold unless your going to be running n2o or boosting it.
What plugs are you running now?

Guys, there is a protocol to follow.
READ your plugs, if the flame burns too close to the tip, then yes you need 1 step colder, if the flame is firing correctly, it is not necessary.
That is how you determine if colder plugs are needed.
The cam plays a role (DCR).
