Possibly slow to generate any boost?? but looks like it follows whats requested. Was it full throttle/load? Manual car/dsg??
The others on here will know more.

To my untrained eye that looks OK. Others will know for sure.

What is your concern?

The two things I would look for are fuel pressure and boost not following specified. I can’t see specified fuel pressure but actual appears to increase and then hold (rather than drop off) so looks fine. Boost seems fine too.

Just not as happy as I could be is the issue tbh.

It just doesn’t feel right to me.

With the mods I’ve got it should be much quicker.

What mods has it got?
How does it feel to drive?

Whats the standard boost for the edition 30? from that it looks like it doesn't generate much untill about 4500rpm?

You need someone on here who's more familiar with what it should be.

People often multiply g/s from the MAF by a fixed figure to get a rough power figure.

That might help you estimate what power the car is making. I want to say 1.25 for flywheel power and 1.1 for wheel but worth doing a quick search. Obviously lots of different factors at play in estimating like that.

Would around 310 flywheel bhp be what you would expect?

Yes the boost profile looks odd to me.  It should be hitting a bar of boost way before 4000rpm.  It's only giving 0.4 bar at 4400rpm and then suddenly jumps 1.25 bar at 4880rpm.

A stock ED30 should hit stock boost of 0.9 bar by 2500rpm, a peak of 1.1 bar by 3000rpm and hold 0.9 bar to 6000rpm, and then gradually taper off.

Judging by the 1.5 bar peak at 5400rpm, I'd say it's a remap.  And not a good one.  Either that or there's something seriously wrong with the boost control.

Would I be correct in saying the boost is controlled by the evil demanding what it’s been told to.

Then obviously the n75 controls the boost ?

What would you guys recommend I do about rectifying my issue ?!

Any hardware culprits ??
