Looks like the SP578's that are replacing the SP542's aren't the same heat range. LMAO... I can't win... I'll be ordering the Ford Performance plugs today. Hopefully I can pick up a set today at Tasca Ford. If not I'll order online. Thanks for the heads up guys!!!

Just a heads up. Installed new Ford Performance plugs and the car is back to normal with no more misfires. Thanks for all the help!!

Well I took the car out this morning for work and again I had the engine light flashing then go off while driving. This happen after I went WOT on the highway. Seemed to have a very small hesitation then pulled good. I'm not seeing any knock at all. I'm starting to think it may be a fuel injector. Or possibly the octane booster may have damaged an O2 sensor. I'll check the codes when I get home to see what comes up. Thanks for looking...

Do you have a non-meth tun to run on your hardware?  if so drop down to that and put it in manual shift mode and do a 3rd gear sweep from 2500-6000 rpm and check the STFT .. it should be obvious at that point.  Gluck

Thanks... I will definitely try that!!!

So I took the car out again last night to see if I could get a code to come up. Unfortunately no codes but I definitely have a hesitation and sputtering issue. This only happens when I attempt to go WOT. I'm thinking after having to replace the spark plugs due to the orange coating from the Boostane. Perhaps the O2 sensor/sensors also need to be replaced. I'll pull out the wideband sensor today and see how it looks. My question is can the O2 sensor go bad without a code showing up and can a bad O2 cause these types of issues. Thanks in advance for looking.

How many miles on your SHO! The sputtering sounds more like an (COP) ignition harness connector issue IMO!
I would double check the connectors to verify that there fully seated and the (red tab) snap into place.
I would also check Spark resistance with a multimeter to verify concern..

There are 2 Front wide-band 02 sensors which should be replaced in pairs and have the same part numbers.
I believe the Fault code needs to be set for at least 3 consecutive times before a code will be emmitted IIRC. Z

Car has 29K but motor has approximately 800 miles on it. Engine was replaced by ford due to LSPI. I already triple checked the connectors for the coils.

Soo sooooooo ##@#ing this ... ^^

I like Fords,  but I hate ford built in diagnostics.   I had a very bad Injector dumping fuel,  no codes... Had bad plugs,  no codes,  Had a bad wastegate that was stuck basicly closed no codes. 

Get it up on a rack and pull the O2's in front they will have the worst impact. 

Z... could this be a bad knock harness? Like we have seen with the rubbing issue?

if you did not replace your cats with the new block,  you can likely expect some reduced life from the goop :(   .. on the other high low flow cats yield good gains :)
