I think I'm the only one that really does that.

I only do it because I commute nearly 200miles a day.

I only point it out to show how much room people have to play around so they get aggressive with their timing (using your det cans of course).



and BIIIIGGG facepalm to OP.

+1 on facepalm. I was about to +1 on the suggestion that you check your static timing calibration until I saw that (you did check it with a timing light, right?). Check your duty cycles. I'll bet they are near or above 100%. Above 80% is pushing it. You gotta keep an eye on da deuti cyclez yo.

Don't wait. Put them in NOW and retune. Or disconnect your wastegate.

Except that installing injectors has almost nothing to do with installing a clutch. I could understand if you said "I have a new rear main seal ready to go in when I put in the new clutch," but the above statement makes almost no sense.

+1. If you're doing a bunch of tuning anyway, you might as well do it on the injectors you're going to keep in the car long term. It will save you some duplicated effort.

As far as I know, it's basically the same as my setup. But yes, I know all engines are different and I shouldn't just assume these things. At least now the next n00b may come along and see this thread and not look like an idiot

I know the injectors don't rely on the clutch job, it's just that I've got the long weekend to do it, so I'm doing the harder thing first. I don't drive the car daily, so nothing will break....yet.

I'm not usually like this, believe me
