Why not ask Terry himself, who posted in a thread titled "Who has blown an N54?" a few weeks back?

I see. Thought you were stating more than one N54 have blown with Terry's tune. There is only one case, and a very extreme case at that. Far from a stock turbo car.

You don't see incidence rates of injector and HPFP failures as being related to heat or duty cycle? Honestly?

I can't say yes or no. Because there is zero proof of what you are stating. I know people with 100% stock N54 cars, that have had 3 or more HPFP's replaced. BMW's fuel system is a complete failure on the N54. They know it, but will not do full recall on the system.

The statement suggested that people who add hp can find other limits, and experience higher incidences of failure elsewhere. You don't agree?

I don't think its the higher power. It is the combination of a sticky drapstrip, stick drag radials, and hard launches. Even with stock power, with those circumstances wheel hop can occur and half shafts will break. It is not just 335i's that breack half shafts. I seen mulitple e46 M3's break half shafts at the strip, with stock power.

You did in your actually post. Some people are lazy and don't click links to get the whole story.

There have been emails released and Terry did ask hime to run race gas. Also owner had ask to remove the failsafe Terry had in place to protect from this very situation.
I don't think you are attacking Terry. Just like all the information to get out.
