[sasha021]

my nissan r33 ,ive changed pod k&n fillter ,i new iridum spark plugs ,boost control to 11 psi .when i go 5000-7000rpm i sometimes get a popping noise throw exhust. Pen lugs are set at 1.1. the problem when i accelerate slower its ok . but when when accelerate full throtle at arround 5000-7000rpm i get poping.

it fills like to much air & fuel is going into the engine & coses to cut out .cars got front mount intercooler & apexi exhust.

IF ANYONE CAN HELP IT WILL BE VERY HELPFULL

is that when you let off at 5-7k? Sounds like youre just burning the excess which is making you go pop due to running rich...

But i unno

Pull the plugs out and either gap them down to atleast .8mm or buy some bkr6e pre gapped at .8mm. If this doesnt fix it u will need new coil packs.

Or u can drop the boost back down to stock

Buy coppers next time and gap to 0.8mm. Kristina are horribly expensive. I buy a set of copper plugs for mine for $20 and I run 18psi all day everyday. You don't need iridiums as has already been said, coppers will save you a bunch money

Drop your boost. Stock turbo stock ecu 11psi you will hit r&r. Gap your plugs to .8 and run 9psi

^ as already said before buddy, it will probably bee your ccoilpacks. Either do a refurb on them or buy some expensive splitfires. I would just do the refurb and drop the boost back until I could afford the splitfires buddy. Get a video up of it on youtube and post the link in here if your still concerned.
