Wierd Misfires. 2g Tsi
 

Ok so i been having weird misfires ever since replacing my old T25. 157k, New plugs, 450cc injectors, stock SMIC+piping, 1g bov adapter+ bov, replaced front bank o2 sensor, old stock cat. converter... While im driving on the highway (without boost) ill have a misfire and a weird smell will fill the cockpit once an awhile, my car wont boost past 5psi sometimes without misfiring/fuel cutting but will sometimes hold at 8-9 on 3/4 throttle but never will allow me to WOT. EGR is blocked off and fuel pressure solinoid removed, but these things where still happening before I did the EGR mod. I haven't had a chance to boost leak again after a failed attempt with the cheap one I made before, but i couldn't imaging a boost leak limiting me to 5 PSI on such a simple setup?? This was never a problem until I replaced my turbo with a T28.

Things I plan on trying or possible issues/suggestions.

I would like to Boost leak test again,
Should I RTV the BOV gasket?
Should I RTV the EGR block off gasket?
Buy a new coil pack?
I have a FIC injector seal kit I have and need to install...
I have/waiting on FPR and install that...
Would the injectors be bad?

More or less I'm looking for more opinions so I'm not spending money on pointless things I dont need replaced..I've already dumped 2k on this car and its still stock, WOW.

Update: 3 random misfires/bogs in the drive through while car was fully warmed up. thinking coil pack right now.

I have a coil pack for sale pulled from my car. Did you change wires? check gap? What brand of plugs?

I'd say wires if you haven't replaced them.

#3 wire was bad. haven't replaced them, didn't know they where so old.

That used to happen to me...I was running super lean. what your AFR at? check all your injectors the normal stuff.
