Hi all,
I have recently fitted a egr blank, turned the boost up to 1 bar and turned the fuel screw in on my abl engine. The van pulls like a train up to 3000 revs but dos'nt seem to pull clean up to the redline from 3000 revs even though my turbo gauge is still reading 1 bar. is this normal?

How do you mean 'clean'?? Smoking, or rough running......

BTW - it's a diesel - why are you red lining it??? I:

No neeeeeed. Change gear and the turbo will work and you will be off like a rocketT:

i dont redline it everywhere. it just runs rough and lacks power between 3000 and 4500. im sure its something simple. was just wondering if anyone had the same problem or could give any advice.

Mate - without wishing to sound dumb - I say again, it's a deisel...... they're not supposed to be revved, hence the silly low 'redline' in comparison to a petrol.

My best guess is that you've just cranked up the boost to 15psi and upped the fuelling expecting results.......

It doesn't quite work like that.......

Perhaps go and take a gander at all the work that's been done on this - there's a whole lot more fettling to be done to get the best balance of feulling and boost, as one without the other is just asking for trouble.........
