Thread: Next performance mod?

Xcessive Mani, Tuneable ECU and dyno tuning session.

did I miss the crank pully? I dont see that there, that would be my first change.

What would i be changing to? I am hitting 8500+ on the regular

I see that gspec sells a light weight crank pulley but i have read that keeping the factory DE is a good idea due to the dampening affects it has.

Also, purchasing a xcessive IM, would i be gaining any power if i purchased just the upper plenum or would i have to purchase the upper with the lower runner section too.

Another thing, i noticed while i am going WOT my AFR is staying around 15:1 which is not good for making power since it is running very lean for wot. I need to get tuned asap! Overall the car is running very strong after 3k rpm, i am thinking about degreeing he cams but not sure as to what i should set them to. I know my friend was running +6/-5 and he said that is where he made the most power.

keep beating on it and that motor is donezooo

the tune is so important to make power and people always skimp out on it

i understand that, i do not go wot in it anymore after seeing that.

Bigger brakes and suspension upgrades!!

I have the bigger nx2k brakes, and im sitting on d2 coilovers

Your next mod should be a brick under the gas pedal so you can't do much more than idle. That is lean as fuck! Get a realtime ecu, sell the JWT, and use the funds towards an intake manifold. I would not beat on that motor. Either that tune is terrible or your wideband is mot accurate. I would try another wideband just to verify. How do your plugs look?

Shoot me a PM if you would be interested in RT ecu for your setup.

Having an RT ecu will allow you to make the changes you need to the tune now and will also allow you to change the tune in the future if you do upgrade manifolds or any other part on the car. You can do it all in realtime and also can have full control over your vvl engagement points through the ecu.

If you like your oil pump in one piece, I would stay far away from undampened crank pulleys...
