Here are my map and a list of my engine mods. I have purchased this car recently. It tends to stumble and loose some power at 5500 and up. Still pulls good but it hiccups and doesn't feel like it pulls as hard. I am short on cash otherwise I would go and get it tuned with a wideband. That will be in the future because eventually I would like to do this my self. Please take a look at my mods and maps and give me feedback. People with similar set ups, your input and maps would help greatly.

Thanks

Oh ya, I also have a Auto Meter Air/Fuel Meter and at WOT it shows 2-3 green rich LEDs at 5500. I have only taken the engine to 6000, but it still reads rich.

OEM narrow-band sensor reading AFR meters (like the Autometer unit) no matter how expensive, are not accurate enough to rely on. You will need to look into a 5 wire wideband sensor and Wideband control unit before you can safely adjust your fuel and timing. The other option is to tune at a dyno that has a Wideband function available.

Save your engine. Tune conservatively.

I understand that. Right now I am short on cash and looking for a good dyno shop that knows how to use the PFC in the Washington area. I would like to see other peoles maps with simialr mods. Or get feed back from people as to how my maps look (how they are setup). I have compared my maps to the ones in the sticky and it looks like my fuel maps are greater then some at higher rpms and load. I have also noticed that my timing is much different then others with ported motors at the high rpm and loads.
