R33 Boost Problem

[boostn0199]

today i installed a turbosmart boost tee to my r33 which has stock ecu, and i adjusted itand it was running fine on 12 psi then suddenly after a few hours when i put my foot down and boost reaches max the car starts to jerk and not feel smooth it oonlhy happens on full boost. so i put back the stock boost soloinoid and its still doing it andnow im realy confused since i have not changed anything else any ideas?

The reason why that is happening is because your:

Coil packs

Spark plugs gapped to 1.1 or 0.8mm

Stock ECU

Rich & Retard

Boosting over 12 psi is when your car starts going crazy! Because of the MASS airflow coming it it will cause this to happend.

Clean/change your plugs, then reset your ecu.

Assuming your plugs are .8mm, if not, change to .8mm.

since it occured after fitting my boost tee im guessing its Rand R but it doenst go away when im running stock solonoid now is there something i have to do to get rid of the R and R, i reset the ecu aswel

i have the same problem but mine loses power between around 4k rpm to 6k rpm. makes a popping sound like the fuel isnt being ignited at the right time due to spark plugs or coils so ill be taping my coils and putting in platinum sparkys regapped to 0.8 to overcome this. ive heard R&R only kicks in over 14psi so i suggest going with the sparks and taping coils first. im guessing it does this because the old plugs arent gapped for such a rush in fuel.

yeah i understand all this but the question is that my car was running fine before on 10psi with solonoid and now after the boost controller ive revereted to the solonoid it doesnt run with it so how could the plugs be an issue if they were running as they were before with the solonoid

pull them out and have a look, they're probably fouled

myne went R+R with only 10psi, will be slighly different for ever car but

just took em out cheked them,plugs are fine im guessin now that its the coil packs? anything else it could be?
