Don't even mention to Jim Wolf that his program runs rich...I did and he went ballistic on me. You can get him to do a custom program for you but he will want your car and lots of money. Just get an AFC and dyno tune it you will be fine. A custom ECU is not a good idea in my opinion anyway since it will be specific to your current mods, it will be a big hassle if you want to add something else major later.
About Greg Dupree's 280, he does NOT have a custom program just a raised rev limiter. That's it. He runs a fuel pressure regulater to up the fuel curve for higher boost.
