If your using pps, ive found with some thicker products, that removing the screen in the lid and just straining the paint helps sometimes.
Dont know if either of those could be a possibility for you but just an idea

Sprayed PPG's DAS sealer , DBC base ( 1:1 ) with one that has the LVB cap I normally use for base , and clear with my other LPH 400 1.4 that I only use for clearing , and came out very nice .
Also Sprayed some PPG's DPS Primer with my W 400 1.4 I converted to an LPH and it sprayed it with no problems .
I use the 3M PPS cup & liner system , but i hardly think the factory cup is the problem .
Color was PPG # 5377 , Pewter Metallic , which is a very popular color on GM trucks .
This is the job I shot with the LVX w/ both guns today , pics arent the best as they are pixelated from my phone .

I switched out my 1.3 needle to the new 1.4 needle and as you can see it shoots just fine
When I ordered my 2nd LPH 400 LVB I made the mistake on the 1.3 and had some of the same results you are having , and the 1.4 needle changed it to my liking !
