So I had manually boosted my car with 12lbs on stock everything except intake, I would hit full boost at about 3500-3800rpms maybe, I then put on my 3" turbo back exhaust on recently and ran the caar with 12 lbs and it was spooling up fast at around 2800 rpms. So now I am hitting boost at around 4 grand and I am not sure why it is taking so long for boost to hit, I have been keeping good care of it and the cel is on but thats just throwing a code 43 which is egr related i believe and it was like that when I bought it and it still pulls alright I am just not sure why the all of sudden delay. I did just recently put in ngk bpr7es spark pplugss with a gap of .032 but thatt shouldnt effect anything to my knowledge. So is my turbo just acting funny and not knowing when to open the wastegate because I do notice the boost gauge fluxtuating once in a while going up aa pound and then back down a pound but this is veery rare.
Thanks,
