New here 2013 black on black PP w/livernoise 91,93 tune

Welcome to the forum!  Sounds like you're already off to a running start with the LMS tunes :)  What is your impression of the SHO so far?  Post up some pics so we can all ogle your ride!
 
Welcome!!
Glad to have you with us.

Big things happening all over the forum and a lot of great members to exchange knowledge to advance the platform.
 
We'll I traded my 05 SRT 10 for the SHO and this is the first awd vehicle I've owned. I love launching this car especially now with the tune, super torqy. From what I hear the next step for these is downpipe, filter, 170 tstat, and last but not least meth injection.
 
If you haven't already gone a step cooler on the spark plugs and gapped to 30 consider it.  Helps prevent misfires and spark blow out at higher boost.  LMS recommends it.  Downpipes will get you a much earlier spooling of the turbos resulting in earlier power and torque rise.  LMS can modify the tune for the DPs to get you max performance.

Motorcraft SP-534 Iridium plugs or SP-528 Platinum plugs will work... I'd recommend the iridium

I agree.  I went with the 534 and am very happy with them.  I am a little confused regarding temperatures.  From all the info I could find,  the 528 and 534 are the same temperature.  Just different materials.
 
OK.  So the NGK's that BPD uses and/or the Denso's that Crash, Darreli and FirstSHO use MAY be a step cooler than the stock Motorcraft.  But as far as I know, the 534's and the 528's from Motorcraft are the same temperature.  I'm fine with my 534's even though I don't think they are a step cooler.  They are approved for my tune, they are gapped at the right gap and they are a step up in material from the 528. 
 
The sp528 and sp534s according to a few online stores show them both to be an Iridium plug. I do think.however the sp 528s we're replaced with the 534s due to random misfired that were occurring with the 528s
 
It's unbelieveable.  I just googled the sp534 and sp528 again.  Between PEP Boys, Jegs, ORielly, Autozone, Amazon and Ebay, no one agrees on whether either are platinum or iridium.  I default to the SP534 being the latest and greatest.
