I installed GTR plugs as well, I forgot to mention it (i did so much i cant remember anymore). So no heat exhanger comes with the stillen kit?? or it's not sufficient enough?

The heat exchanger from the kit is very undersized and will heat soak in a hurry. Get the bigger one and a CSF radiator and the car will be much happier. The Stillen kit has serious heat issues. This way you're at least taking care of a few of them.

Thanks so much Chuck, much appreciated dude. So you recommending the frozen boost heat exchanger for the kit and a CSF radiator for the car? Also, I know you said meth is not needed, but does it help with regulating the fuel and maybe push little extra ponies LOL.

Meth doesn't regulate jack ****. Meth adds octane to pump gas. You would have to have a map tuned for the meth where it gets leaned out to compensate and you can be more aggressive with timing. You'd gain some power and it would run cooler, but if you have a meth system failure or a clogged line or any other interruption in flow under boost you now need a new motor.

Frozenboost heat exchanger is here :)
Air to Water Heat Exchanger

This is the one I ran and the GTR plugs are a very good idea also. I had the same.

You know what Chuck, I head that "you will need a new motor" phrase so much that I had a spare engine sitting in my garage before touching the one in the car.

Start building it to hold a LOT of boost. :stirthepot:

hahaha u read my mind, I am already doing some research about it. So much for keeping the car stock after 5 month of owning it.

Thx ANMVQ & Chuck33079 parts ordered and arrived at my friend's shop. I found a another tuner who said to bring the car to him and he will install the parts and lean her out to correct the running rich issue. He also told me the starting issue is probably related to too much fuel dump which he will fix as well. Last question guy, how long do it take to tune the Z properly??? Days? Hours?

My tuner spent a day and a half on mine between the dyno and road tuning.

Mine did also a good 4 HRS, The tuner is right about the starting issue, That and the hot start values are probably wrong :/

Mike took 8-10 hours over a weekend to get it all working right. The bulk of it goes fast it the fine tuning it that takes the most time.

Yep.

OP, take a copy of the newest throttle map from the thread in the tuning forum and make sure the fan settings are lowered dramatically, both with AC on and off.

I have 1000cc injectors and don't have any issues starting it cold or hot. Tuner needs to spend more time fine tuning it.
