Re: From "stay tuned" to T U N E D !!
I think the car protecting itself from high loads on a cold engine is a very real possibility. Im actually surprised people don't warm up their cars before putting them on a dyno. Didn't know that wasn't I thing.
I am very conscious of going WOT on a cold car from my turbo VW days and still watch both water and oil temps carefully. I know at our autocross events, people always start their cars when they grid up for their heat. Even though the runs are often less than a minute, no one wants to do a run on a car with a cold engine and cold oil.

Thanks and FWIW the dyno showed 270 hp then 280 on the 2nd, partial pull but I'm sure it makes more than that, I mean look at my buddy's pulls:
1st was bone stock from May
2nd was just the cat-back
3rd was w/ the piggyback turned on
The exhaust netted 17/31 alone but combined it went from 277/330 whp & 283/353 wtq

You want hot oil and cold water. Ideally. I never go WoT until my oil is above 120°F.

We'll see what the "butt dyno" in Mexico shows us against my buddy's 330 whp/353 wtq EN, this time same transmission useage
I still think the coils should cone off though but the car not being warmed up nearly at all makes me think the coils "may" be ok

Sometimes butt dyno results are enough to ease the mine.
Merry Christmas don't worry about your car today though relax hahaha

Well apart of me wants to go back there and dyno again but with it completely warmed up.
My buddy thinks it's the coils or tye tune. My thing is this, no signs of an "issue", this investigation could get expensive

Yeah if it’s driving fine WOT… I don’t think it’s a problem either.
I would ask dyno place to see if they remembering it being warmed up and if they’d be willing to redo one pull warmed up for free or at discount…

Late to the party, but to throw my couple pennies into the ring
First off, sorry to hear the day didn't go your way. Always a bummer to have a build up and then run into an issue.
Regarding your tuner's response, the technician in me sees it not as dismissive or dodgy or anything; I see it from their end where I'm sure they've done extensive testing in house with known-quantity cars and (as they mentioned) the stage 1 tune is meant to be conservative and not light the stock hardware on fire. Even with your extra little mods, I'm sure they improvements are out of range for the car/software's ability to learn and adapt - if it wasn't, I'd think your tuner would have expressed concern over the additional mods.
I also see the comment of "should not be giving you any cuts that sounds mechanical" not as a statement that you must have a mechanical issue like engine hard parts, merely a catch all statement for there must be something on your car causing it to cut.
Again, as a tech, having been to plenty of rodeos where a DIY'r has been putting parts in, I can assure you that a lot of aftermarket stuff is not good. While at the shop we do use non-genuine parts, we've developed a knowledge base of what brands to stay away from whole cloth, and even certain brands where you can use some parts but not others. Those MSD coils fall in the suspect category for me, especially if Coating's has seen them poo-poo'd on a separate forum. We've seen plenty of formerly reputable brands suffering from sending their manufacturing off to cheaper production locales.
Regarding what's going on with your car, I'm also in the camp of being sure to get your oil temp up before hooning. For my own car, I've made a habit of not just avoiding WOT when the oil is cold, I'll actually monitor boost and try to keep it below the halfway mark until I've got some oil temp to work with.
But, as far as low oil temp causing a cut-out situation, that should be easy to duplicate - a dyno shouldn't be any different than loading the car up on the road. Ignition misfires are most common under high cylinder pressure (lower/mid RPM, high load, high boost) as it is now harder for the coil/plug to produce a fire in the cylinder. Were you hearing audible misfiring where the car sounded like it was no longer firing all 4 cylinders? A lot of times when I'm chasing an ignition issue, I'll get the engine nice and hot (just from time driving, not specifically rodding on it), then click it in 4th and do a "pull" from about 3K to 5k. You're looking to go max torque, not use the horsepower to rev the thing to redline.
I would try to replicate the conditions you had at the dyno with the MSD's in and see if you can experience the cut again. Then swap in your stock coils and repeat.
Hopefully this is all coherent, typing as fast as I can on my lunch break. This whole mechanic-ing thing is something I can just do but struggle to explain sometimes.
