So being that I need to richen up my A/F ratio, I figured I would look into doing it myself. My question is however our O2 sensor is narrow band, So doing an accurate tune isn't really possible is it, just tune and drive till i'm happy?

But what all would I need. Can I just get the Ostrich 2.0 emulator? or the aldu1 and cabl1 cable with the extremealdl box? I've read about a few free software choices to do it all and that although not mentioned the stuff from the links come with its own software.

Let me know what parts your looking to purchase, I have everything needed to scan, burn and tune practically brand new from moates. I went a new route and no longer need.

What do you have the ostrich 2.0 , the aldlextreme setup? the more I read about tuning the more complicated it sounds.

Can I ask why you need to enrich the A/F ratio from the stock setting?

I have a dual throttle body intake , ported lower and middle , some other things going on but stock internals... and it pulled really hard and I started noticing stalling issues and took shotgun approach replaced 2 of the last few remaining sensors that were old. The coolant temp and the oxygen sensor , after doing so I noticed my problem with the intermittent stalling was actually a broken clip on the ignition coil connector. So everything is fixed now....

But after replacing the sensors the performance is noticeably down leading me to believe that it is running leaner.

Yes I have those items. Even if you don't tune yourself it makes it much easier for someone else to tune it for you. I used Sinister, I was able to email him the data and he would email me the adjusted tune that I could burn to the chip and have running in the car in 2 minutes. It also allows you to make adjustments thru your laptop while driving.

You can always use WinALDL to see what your fuel trims are doing. Even with the narrow-band O2 sensor your fuel trims will be adjusted higher if your car is always running lean. I believe the fuel trims only affect closed loop though. You can always try an adjustable fuel pressure regulator too. It's the brute force method but it would help to diagnose the issue before spending alot of cash. A penny placed above the spring inside the FPR housing can be a free test. The penny shortens the spring which adds more pressure to the diaphragm.

i just found another post talking about the penny trick and decided thats what im going to try out first. Except for instead of a penny i'm going to use washers due to copper and aluminum. I'll experiment with 1 and 2 or just a thicker washer and see which I like better and im pretty confident it will get me where I want to be.
