New stall problem. After install

[Tw0LeGiT]

hey i just installed popes 3"dp and corksports 3'' exhaust. now at random times at low rpms or idle it stalls.
any ideas on what it could be?

 

[CHIQLES]

lower back pressure

 

[CHIQLES]

plus its summer air is thinner so everybody rpms are lower and dipping I see everybodys having idle issues

 

[Tw0LeGiT]

are u 100% this is the problem? and is there anything i can do to fix it?

 

[CHIQLES]

no I cant say that but its a very good possibility.

 

[Tw0LeGiT]

well it looks like there a bit more. i went out today and was pushing it. when i hit about 6k rpm it started hiccuping, it dies then full boost again in a matter of seconds and it happens repeatably. in the same boost. like 4-5 hiccups. but the stalling i have figured out. seems all u have to do its gear down properly to 1k rpm then clutch and its stays fine. but i cant go from 5k rmp to neutral or she dies

 

[CHIQLES]

same with my car it doesnt even bother me it only will flicker the light if i rev it and let the rpms slam down...

 

[CHIQLES]

well the hiccup could be coil or fuel cut do you have the torque program for your phone it could show you if your maxing out your MAF signal

Or it could be the stock tune

Could be time for an egr clean as well

hey guys i was out today and 2 codes came up. p0355 and p0301. I'm guessing there to do with my install. I had the rad off, manifold off, turbo vacuum lines off along with the turbo. plus a new Injen intake. also when i put it back together, i didn't notice a puncture in the rad. so i lost all my coolant and it overheated on a trial run around the block. so i pushed it home... any off these could cause the problems? one of these components not being tight enough? or something overheating?
its runs okay now. its when i hit 5k rpm it hiccups/feels like misfiring. and rough idle, it will sit at 800-1k rpm sometimes and be fine. it just will dip down to 500-200 rpm and stall if i don't gear down

well, the p0301 is cylinder one misfire and the p0355 is something like ignition coil circuit malfunction
