Misfire or cut out at 7,000 rpms?
I running a t3/t4 with a .63/turbine and .50/compressor on a stock b18b with a custom ramhorn mani. My friend street tuned it 1 week ago @12lbs with crome. My a/f's are rich at 10.7/1 @ WOT. We couldn't tune partial yet (waiting for crome pro). Didn't have the Ngk 7's, so we used my zfr5f and gapped to .23. The car hasn't missed until a day ago. I couldn't find the ngk's so i got some cold copper champions and gapped to .25. I'm still getting blow-out or misfire.

Re: (moops vs moors)
Haven't put on the dyno, but i have stock ignition and just replace with oem wires cap and rotor. I'm running pump gas 92. My timing is 11.5 degress BTDC @WOT. It misfires more when someone is riding with me

well if your making over 300 hp you are experienceing lose of ignition due to the fact stock ignition can only go s far u need to get a msd blaster coil ss. with a new rotar & cap it will cost u about 150$ all sead & done & u will be good to go.
my stock ignition took me up to 320 then had to upgrade.
the car would just fall on its face then kick back in

Re: (NewLs'er)
why would you go from .23 to a .25 gap when you are misfiring... if anything go smaller................................... get some fresh plugs while your at it...

get the NGK 7's gapped at 0.30.. And you can street tune partial throttle just fine without crome pro. Make sure your ignition system is healthy, stock ignition is fine.. No MSD needed.

you need to get -7 plugs. it coudl be getting too hot and it could be causing slight detonation as well. there's a reason for the colder plugs on turbo cars.
try getting -7's and gap them to 25 and see what happens.
if the -7's have issues then gap them to 20 if still ahve issues, then JUST for testing purposes gap themt o like 12 and see if it fixes it. if it does, then your coil is going weak, replace it. if not then you have other issues.

Re: (Built2.0Lude)
I've replaced cap rotor plugs wires coil and gapped from my plugs .20-.28. Still misses. It first happened 2 weeks after I street tuned it. My setup and everything I've tried is in the top of this post. Could running to rich be a possibilty??
