hellpppp,,,i got a misfire only in boost! Ok I have a ls2 with a tc78 and it runs great, traps 113 in the 1/8th blah blah. But tonight I was playing with my boost controller and 2 step to get ready for the track tomorw night all was well, I madea few passes on the road out front and everything was dandy then on the way home I rolled into boost and it felt like a cylinder is dead.. I hve great ful pressure at the rail, and no blow by at idle. It runs great part throttle just anytime I get into about 0 lbs of boost it stumbles. I have tr6's (about 100 miles old but I know that doesn't matter),great supporting mods like double springs,e85,80lb injectors running 100psi at 12lbs boost,runnin off 11_12lbs wastegate right now. My boost controller didn't want to work.
I'm thinking while I was in the shop playing with my two step I Fouled a plug to two. But would a foul plug run good on idle and part throttle? Ugh I work till 5 tomorow and I was surpost to be at the track at 7 so I'm stressin out right now. Ill pull plugs once I'm. Off tomorow but I would like some experience people to tell me what they think.

I can't see a injector being messed up and only making it miss up top? Wouldn't it miss at idle if that was the deal? I dunno I still think a plugs fouled andboost is blowing it out.(hopefully)

Ok cool plugs it is. Since I'm on e85 I've heard that fuel lines break down sometimes so maybe I have some junk sitting on top of my injectors. So ill pull them and shoot some brake clean and shop air in them. Hopefully that'll do it! I got a lot on the line tomorow ! I got'ta make it to the track!

We had a car come in like that and it turns out that the previous shop had shaved one side heads more than the other 
We had to have the other side milled down and things were fine after that. Only issue we have now is his supercharger belt is slipping over 4500 rpms

Ive went through two sets of TR6's in 5,000 miles. Single turbo 6.0 on E85 gapped at .024. Switched to Autolite 103's. So far so good.
Same symtoms at you when they went bad.
