Misfiring/bogging while building boost
Alright here's my problem, im at low rpm, then i start to build boost, then around 5-6 K i begin to bog somewhat, boost doesn't feel as smooth when it starts to spool up, almost like its hesitating.
Although currently i have high fuel pressure it shouldn't affect my performance to that extent. I checked cylinder #1 spark plug and it seemed fine, i will still most likely replace them. I also had the ignitor replaced in the distributor before the car was even tuned.
So i'm wondering what other issues may be causing this problem, i will check tomorrow once i get my plugs to see if it keeps occuring, but i'm wondering for future references what else it may be. Also the wires are new too so i highly doubt its them.
thanks

car was just freshly tuned about a week and a half ago, if anything i'm thinking my current fuel problem that i have may be the issue but to cause the turbo to hesitate alittle i can't really see that

not 100% positive, but i know they are the NGK BCPR7E's and i have them gapped around 28-29

it was running PERFECT when i got it back, right now i believe i'm running 65+psi fuel pressure at idle (not too sure cause my gauge broke and the liquid filled is comming in tomorrow)
