BAD NEWS
After some searching for a vacuum leak, I couldn't find anything. So I decided to let the car run and unplug each coil for a sec to see how the car responded, cylinder 8 didn't respond. So I tested the coil and coil was good. Then pulled out the spark plug and it had oil on it.
Did the compression test and Cylinder 8 has low compression (90psi)
This explains all the oil in the throttle body, I cleaned out my K&N filters 2 months ago and there wasn't any oil in there...
I had the car for almost a year & put 16K on it without a single hiccup until I got it tuned less then 30 days ago & thats when all the trouble started
I didn't even put 300 Miles on the car since the tune...
What should I do?

I don't believe the fuel filter been replaced.
BUT
I spoke to Jerry and he has offered me to ship my car to him and he will replace the piston at a very low price - I wont have to pay for the actual piston, But I will have to pay for the rest of the parts like head gasket, head bolts and other misc. parts and a little labor.
I am trying to decide if I should send my car over to Texas OR just pull the engine and get the work done at a local machine shop.

where did you beef up the tranny with Kevlar internals? how much? By who? How's it holding up? Does it feel different? Thanks.. Hope you get everything squared away with the motor.

Honestly every once in a while the shift isn't exactly smooth, nothing serious but just not butter smooth - does not happen very often
Thanks, i'm working on getting the car back on the road

This sucks, I just got my pulley and tune and now don't want to install it. The day I got it and flashed my car with it I started it and the moment I started the car 10 seconds after idle it started knocking. I was like holy **** I haven't even moved the car and it started knocking!! So, I decided to return it to stock to see if hopefully the knocking would go away. Well it did!! so I decided to reflash again with the performance tune and started the car. Well it didn't do it so I took it for a 5 mile ride/cruise. Well on my way home I rolled down the windows and got to first stop light and it sounded perfect and felt good(smooth). As I get to the second light I hear knock knock knock I was like holy **** it still feels very smoth but it's knocking like an mf'er. Well I get home and pull into the driveway, shut the car off and open the hood and start scanning around and come to find that the AC compressor clutch gave out. See the c clip in picture..
maybe it's a sign not to remove the pulley and not do the tune.

Fuel filter is siting with the fuel pump or am I wrong?
I'm asking as I installed a new fuel pump about 5k kilometers and wonder if the fuel filter is part of it.
What can do in order to prevent the #8 cylinder problem?

I ordered just the supercharger pulley and tune and currently only have the Heat Exchanger and Johnson pump with K&N's. Do you guys recommend I do bigger injectors and change fuel filter just to be on the safe side? I'm at 70k on the clock

I would deff. put a smaller s/c pulley on it! I personally would do injectors but I will let other more experienced members chime in.
As far as my issue goes, I have decided to pull the motor out of the car my self and look at how much damage is done.
I have almost everything drained and unhooked from the engine and the torque converter un-bloted, hopefully the motor comes out tomorrow!

Did you upgrade from stock to your current setup in a single application or did you upgrade part by part? Running meth? Larger intercooler (TTM)?
I've got the 185 pulley sitting in my garage taunting me to put it on.

ALL of the mods were done about a year ago and the car ran 100% for the whole time.
UNTIL I decided to go with a smaller S/C pulley and get a tune and after that the engine just started to have issues for a couple days and then the cylinder 8 issue within 30 days of going with the smaller S/C pulley.
I think the 185 lower and smaller S/C PULLEY might be too much boost.
Is anyone running this setup?
Yes I had a bigger intercooler but no meth.

Too much boost, hmmm. There are a few cars running around with comparable setups. What were the ambient temps when you did your first pulls after SC pulley install and tune? What leads to piston failure, lack of fuel, aggressive timing or both can cause detonation.
Do you log and have an AFR gauge you can monitor? Logging and having the equipment to monitor AFRs are a must when modding a car to your level along with meth for the added security in the form of octane. Having the ability to share log files with your tuner needs to be a priority.
Imagine going to the DR. for a stress test without any monitoring! Best he could do is guess your ok, or stand over your dead body.
