Sounds like Jak did have a concervative tune on the car, but the owner wanted more boost. Can't blame the tuner for giving the owner what he wants, hell, I have asked for the same things with my set-up and w/m. I would never blame Jak for anything that goes wrong now... I am kind of asking for it in a way...
I know what you are saying about high pressures and pushing the turbo out of its efficiency range, but I still say that is a different argument and will not argue against you on that point, I am only saying I don't think the 25psi of boost is causing the mis-fire. I think its the di or amm or something like that.
From what I have seen these are only boost spikes, my car did not hold 28spi with t25, it would only spike there on cold mornings in the winter and then fall back after a second or so... I would bet this t7 car is not holding 25spi for long, but only spiking there and holding for a second or two and then falling back.
Whether or not that is the ideal tune is not the same argument as I think the boost level is causing the mis-fire.
I have had pleanty of mis-fire problems myself, but most of them were solved by replacing my plugs and gapping my plugs down to avoid quench. The one time this did not help, my di was bad and I had to buy a new di. Once I did that, no mis-fire at 28-29psi of boost again.
