ok so just like the sig says Im turbo'd with 9.5 to 1 cr stage 2 heads and a big custom cam from speed inc. Ive been battling missfire for some time now its really bad. Im running TR6 plugs gapped .035. oh and my AFRs just went to 10 to 1 and stay there Im guessing its cause the gas isnt burning when its missfiring?? or could it be an injector issue ? I am posting in here since I am turbo'd and maybe someone in here has dealt with this before.

thanks ~Guy

10-1 is little fat 11.4 range is better I run close to that same compression and use to get that misfire on 10-6 now im on 11-5 afr no issues. Allso check your maf and make sure you have zero oil on it it will fudge things up.

That could be the effect of the problem. Everytime ive dealt with bad misfiring its been ignition related. I just had a thread on this a couple weeks ago. I pulled out my plugs and 4 of them on the turbo log manifold side were cracked. Also i was having a wire burning on log issue that i fixed. No problems any more.
