Yup I sure did. Problem turned to be the MAF Sensor

Guess the sensor went bad. Put in a NEW sensor and everything is fine now

I have a wideband o2 setup in my car now and it turned out that my car was running INSANELY LEAN. I was getting some insanely LEAN SPIKES in like the upper RPM's. Spike's would range in the areas of like 14.8:1 all the way up to 15.2:1

Put on the BONE STOCK MAF Sensor and now the car is running great. Had to adjust the WOT Tables just a lil to get the a/f where I wanted it, but the readings were no where NEAR as lean on my WIDEBAND as they were with the PORTED MAF!

CONCLUSION = NEVER PORT THE STOCK MAF... PERIOD

I wish more people would get that through their heads.

Hey, what kind of wideband setup are you using? What are your impressions of it?
I'd like to get something for the GN and use on other people's cars that I've done tuning work on.

Thanks!
