I am currently struggling with a misfire as stated. when I am at low rpm it happens the most. i get above 4k clears up and the car pull very hard. Once I let off the misfire happens again. timing jumps up 34 let off drops to 0 then settles at 10

Idle sounds like a bad lifter( it does not have lifters but sounds like a bad lifter)
raise rpm and it goes away

Mods
Bosch 630cc injectors
JWT C2 camshafts
FI long tube headers
Tomei exhaust
Stillen Gen 3 long tube CAI

any Info would be greatly appreciated. I have a snap on solus edge scanner that i monitor info.
I did have up rev installed but they could not finish due to the misfires. They tuned as much as they could on the dyno. they said the samething above 4k it was smooth
