Can’t get tdi to run right, please help!

So I installed some pp520’s on my golf. Before the upgrade I was getting a little white smoke every now and again, also the cars power/speed seemed very lacking. Couldn’t even merge onto the highway fast then 63 mph, not sure if this is normal for these cars. Got the injectors pop tested and everything before I installed them. The car starts to sputter pretty bad at 1700 rpms and produces a lot of white smoke. Vcds software said my timing was good and I turned my IQ up to 5.2. Vcds also read a p0102 code for my maf sensor. I’m ordering a new maf sensor hoping this was the issue. Any thoughts or suggestions? Thanks!

Have you cleaned the intake recently? Remove large elbow and look into the EGR valve with a mirror and flashlight, clogging will cause loss of power.

Check and see if your intercooler has oil in it.

Try it with the maf unplugged and see if there's any difference, a bad maf will cause really low power, can also cause random hesitation through the revs.

I had one over that I unplugged and the car ran great, owner never bothered replacing it lol

Thanks for the help guys!! I’ll look into these things and let you know how it goes

Checked the egr, and man was it clogged! (I’ve only had the car for a few weeks so this is my first time checking it) I’m in the middle of tearing off the egr cooler and intake manifold so I can inspect/clean them. An opinion on a egr delete? Is there a way to delete it without losing the ASV?

What year Golf? I have dynamic EGR function with a Malone tune - EGR function starts to shut down as the engine warms up.
