TDI injector pressures

[jimfoo]

Got this tidbit of info, so I figured I'd share as I've never seen it posted before.

"Almost nobody really checks the main pressures, cause they don't know how. But what you actually have is a 180/ 240 or a 190/ 280 for the 96-98's. The ALH's have 220/300's. The lower number is the pilot pop pressure. The other is the main."

Yes, I know, and the 190/280B have a different came plate in the pump, a little less aggressive slope.

Since the automatic ALH's pumps have a larger head, does that mean the injectors are different also- higher pressure?
