If you watch my video guys, you will see that I were running rich at the moment I had blow outs...
Now I don't even know what tool to use to gap my plugs, I have two tools and they dont give the same results!
I will post another video soon... I will copy and paste the two videos I've made to my initial post.

From the thread ZZP did what?
They made it up to 900hp with the stock coil on plug ignition.
If the stock ignition will fire under as much boost as they were running, irregardless of plug gap, you should be having no issues even at the stock plug gap.
Unless you are north of 900hp........
Perhaps you have a bad coil.

Well... ok. Here is what I'm gonna do... I'm kind of pissed off. I will widen the gap. Maybe 0.032 is too small and 0.040 is too wide... so I will set them at 0.036!
This is certainly not a fuel pump or injector issue because I'm running very rich when my car gets blow outs!

Well guys, guess what! LOL!
Now they are gapped at 0.036 and my car runs fine now. During my first pulls, the AFR dropped to 10.2 (little hesitations) and during the next pulls they dropped at a higher level, so 11.0 (no hesitation).
Maybe I fouled my spark plugs with the 0.032 gap (too small for my car?). I'm gonna post some pictures soon.
So my car with a 2.7" pulley seems to not like anything under 0.35. WEIRD WEIRD!!
I'm still like what the hell again... I'm so confused. Man those V Power spark plugs are bitches. You just change a little bit the gap, like 0.003 and then nothing gets right!
Just to give you an idea of my AFR if I make a resume:
Gap of 0.032: My AFR dropped down and was peggy rich! 10.0. I got a lot of hesitation and blow outs.
Gap of 0.036: My AFR seems to get more stable around 11.0. First pull I did, it went down to near 10.0 but after a few pulls, around 11.0. Maybe 11.5 during my next pulls tonight?
Gap of 0.040: My AFR drops down to 11.8-11.9... a bit lean!
Now what I don't get is that you just change the gap and then you get FAR different AFR during a WOT pull!
Can someone enlighten me?
I changed once my STOCK plug gap just for testing when I was stage2 and they never have been bitches like those NGK.
By the way, I found out that the round gapping tool was not accurate. Second tool a showed in my video is the accurate one (I used a micrometer to test out).

I had issues with stock gap 0.042" is way too big, I got misfires and KR alot. Not sure what your problem is but the 11.3 AFR seems arlight. When you do a pull like that your AFR is suposed to go down, it's called Power Enrichment. There are several reasons for it. One being that the extra fuel helps to act as coolant during heavy engine loads/higher throttle settings, another being that the unburnt fuel will still rapidly expand when heated giving you some power that way as well. Oh and Buckle up

put in stock plugs w/ stock gap and she seems to be responding well. i havent had time to run it fully yet [ran out of E] but the little pull i did was pretty nice. will post with update.

ok car is still doing it this time even earlier in the rpm band, i installed bkr6e w/ stock gap to see if maybe that would do it but no. any other ideas before i go out and grab another set of the bkr7e?
mods: full exhaust, k&n sri, 2.8, 80s, e85, no cooling mods [cobra h/e will be installed next week], trifecta tune.

There you go guys, my car was running like CRAP tonight!
During a LITTLE pull, 4 psi of boost maximum, my car jerked terribly and it even shut itself off! I was in the middle of an intersection not able to restart my car for like 2-3 times. When it finally started, it stuttered bad. I waited like 1-2 min again.
I started it again then finally I was able to get going but as soon as I depressed to gas pedal more, the car wanted to jerk like crazy.
I think that my spark plugs get fouled after 2-3 days. Because the last time I put them back on, the issue you saw in my video disappeared! The thing is that I cleaned them up at the same time of widening the gap a little. My tune is certainly not good for idling. At idle, I get most of the time constantly 10-16 misfires. This may foul the spark plugs after a few days... What do you think guys?
So I'm gonna buy new spark plugs tomorrow.
Oh and I talked to a mechanic and he told me that I was not gaping them right. He told me that it's bad to tap the spark plug on a surface to diminish the gap. Instead you have to PRESS on the spark plug, not taping it, to shorten the gap.
Well, let's see what will happen tomorrow. The most curious thing is that no check engine light came on after all that crap! LOL! "Hey, my ECM! My car runs fine don't you think?" LOL!

you want the gap as big as possible. sounds like you just had them gapped down too much not allowing for a large enough flame kernal to start. has anyone started looking for non projected tip plugs for these engines?
