3922 is like a -7 for your heads, 3923 is like -6 NGK. NGK and autolite go in opposte directions for heat range. I used the 3922s for a while and switched to the AR3911s (-8 NGK), both worked fine for me. Matter of fact I had 2 sets of 3922s in the trailer.

Lot of numbers for a lousy little spark plug

NGK BP7EFS stk# 3526 is one heat range colder than a TR6 and is the correct reach for a stock style head. It also has 1/2 of the "projected" tip of a TR6. My TR6's were fine at 17psi. BP7EFS should be fine for a street/strip 20psi car using stock style heads IMHO.

mine did the same thing.. if the engine was cold or if it was cold outside it wouldn't run worth a **** until I got a good bit of heat in the motor.. it would misfire while driving and eventually they gas fouled..

sooo.... let say im retarded and all of these numbers dont do for me, hypothetically speaking of course..

i have a set of tr6's that are gonna go in soon, since i will DD the car a bit, i dont want a plug that will suck on the street. The tr6 might be to hot, and the "tr8" is too cold... so a "tr7" is what i need. Since im running a 6.0L head, which one should i run then? The NGK BP7EFS stk# 3526 or the AR 3911's?

Man, all this plug talk is more confusing than trying to figure out cam events!!

I've been running that plug for a month now with no problems....changed from a TR6. Idles and drives great. Boost is up to 14psi and going to 18...fires well through a 10:1 tune as I lean it out with tuning passes.

made some WOT passes on the street...track screen/filter installed with cutout open and new 11.6 psi spring. Boost held 11.8 psi so I am happy now. Onfire, i used what i thought was your setting of the eboost2...30=14psi...at least it worked that way for me....25=12.x psi

boostve table is set at 205kpa and above to 500...max efilive allows....that oughta richen it up if it were to overboost!

becareful of going too rich... it can cause crank and rod damage.... if it were to not ignite in one cylinder it coulb be bad...

That's the correct settings, but they are PROPRIETARY and are only to be used by me.
