Sounds like it will get out of the way in a hurry. How are you connecting the stock lines to the fuel rails?
N, I had major issues on a poweradder car and just could not get it right, I swapped to a SCT meter while we were on the dyno and it smoothed right out. I know AFM had good results with them I talked to Brian a few times trying to see what was going on. I had another shop owner fight a DBX as well and went to a proM blowthrough meter on a ATI setup and problems went away..
I have no experience with them in a NA car. I like the idea of the fully user adj meter, I know PMAS was working on one before they closed.

Where did they leak from?Good luck with the professional products rails. I tried a set and they leaked like a mofo. china junk
Where did they leak from?
