ok guys so i got my evo10 2014 gsr (edm) like 3 months ago and have only
cobb ap
grimmspeed 3 por bc
forge actuator
gfb ajustable bov
(runs on pump gas 91 octane)
thats the only mods it has. and today i got. a costum tune and it would always keep missing in high revs its pushing 24 lbs with 10 -10.5 reading on the wide band 11 max and my tuner said its the spark plugs but i heard a lot of people change them and still have problems i also recall that ams tuned evo runs with stock plugs, the other thing i hear is the new pump relay. just want to solve this without spending on things i dont need.
so im guessing you guys can help out and tell me what you think! got some logs by the way👍

 

What brand/model plugs and what are they gapped at?

 

well they are the oem spark plugs and i havent done anything to them just as they came the car has 7500 km so i havent changed them

 

Gap them down to 0.020" and then report back.

 

thanks man apreciate your feedback 👍
i told my mecanic to install the 3 port grimspeed bc the most stockish way posible and he left the original vacuum hoses (have some boost pills)so i conected the middle port to the turbo inlet the others to intake and wastegate inlets with new hoses and gave it a cruise under full boost and i got p0068 code know without the missfire so called my tuner and he said that he could know retune and he said hes 90% sure he can fix the problem with a retune
be retuning tomorrow at 2 00 pm and report back the results

 

ok so a went with my tuner today and he had a couple of issues with the barometric/pressure and somthing else and refers to the p0068 code means your getting uneven pressure readings in the map and maf in my case so he got that problem solved with the tune got me 3 tunes not sure of the hp or torque becuase we didnt use the awd dyno o well that will have to wait till next week but thanks for your feedback by the way i didnt need to change the plugs👍
