alright, we had hoped the full info would have been disclosed by Mike with his posting because of our long standing relationship, but it's time to clear some things up.
we never once recommended, nor were consulted about the modifications he made. Consulting your tuner BEFORE changing parts is critical, regardless of who that shop may or may not be.
Installing aftermarket injectors, and driving the vehicle without proper tuning is bad on a port injection car, but on a DI car really can be catastrophic
The spark plugs were replaced because Mike didn't want to believe that he wasted money/time on injectors, so it was basically us saying well it's either that, or the plugs. We put plugs in because we were basically being pressed to continue to go down a path we knew would not work.
there was 1 complete dyno pull, 11 miles is from 3 different warm up times, 1 pre plug change (would not rev past 3k or so), 3 or 4 post plug change (would not rev past 3k or so, and a few revisions to just to be thorough), and 1 post injector change (full pull) we are completely disappointed that there is even a remote accusation in what we did while your car was with us
Ultimately, we should have stood our ground on the injectors, we knew they wouldn't work, we knew it should have had stock ones in it, but we let our relationship with Mike soften our approach on what we knew would be an issue (albeit, not to the extent of a rod bearing).
the DW injectors 100% do not work on these cars. not at least when you have the fuel pressure it should have. if you keep them under 1600psi they work, but the problem is that the stock injector at the correct fuel pressure flows more than the DW at lower pressure. So it's not the right path, and since it had our upgraded fuel pump on it wasn't necessary. We let Mike know we spent months working with DW on calibration of these injectors, and no amount of tuning will get them to work at 2300# on these cars. Saying someone "helped us" figure out things we said didn't exist is false. The items we were told to change are not in the 10-12 cars, and do not fix the 13-19 cars. How do we know? we are the ones who found them while working with another DI injector company to develop injectors that will actually work (been revising them for a few years, it's just low priority for them). So no one showed us anything. That "fix" on the 13-19 cars was pirated from a tune we did, and we know as it's not actually calibration changes, but software changes (there is a difference). So we want to be clear, no one told us anything that we didn't already know, they were just 1. incorrect on thinking 10-12's had this (completely different PCM), and 2. incorrect on thinking it fixes the inability of these injectors to open at normal fuel pressure.
So, when you add the fuel contaminated oil from driving without a tune for the injectors, the horrific way it ran under a load with those injectors and the a tune for them, it's easy to see why it spun a bearing.
What is NOT being posted, and is on the edge of disappointing and infuriating is Mike not bothering to post that we offered to pull the engine FOR FREE, tear it down FOR FREE, and, depending on what it was, possibly repair it, you guessed it, FOR FREE.
instead, there's some praise for someone's advice that was not advice at all, and someone that's charging you to do work. Not cool.
Stuff happens, things break, but to disclose only selected parts of the story, twist things or say things that aren't true, and make an accusation that attacks our honesty and integrity is a big deal. We don't care that people know that it spun a rod bearing, it was together over 5 years, set records in more ways than one, probably had more dyno pulls than another other SHO on our dyno (besides our original tuning development stuff), driven hard when the chance arose, and has done so without skipping a beat during all that time.
