what i did was bought a quarterhorse tuning device, and a innovate lc-1 wideband setup and binary editor(tuning software) went to eectuning.org and paid someone 100$ to write a tune for my car. there are some people on that website that live and breathe tuning. the first tune i got on my car was a gain of 23hp 19ftlbs over the stock tune. i just put my motor back in the car and got it started last night. i am in the process of getting this setup tuned right now. the guy i have doing the tune doesnt just tune for WOT, he will keep going until you are satisfied with the driveability and the WOT pulls. all you do is drive the car and datalog with the tuning software, then send the datalog to him. he sends a new tune back, you load it up and go for another drive. takes a little longer than a dyno tune but in my opinion you get a better result because the driveability gets tuned also. it was prob about 610$ to get everything that you need. 250 for quarterhorse, 200 for wideband, 60 for binary editor (tuning program) 100$ for the tune. then 100$ for any tune if you plan to make any major changes. the nice thing about the quarterhorse is you have control over everything in the computer, you can run any injector with any maf. i am running a 3.5 inch aluminum tube with a 2005 mustang slot sensor and 42 lb injectors, these are not calibrated to match each other. the maf and tube cost me under 50$. you can turn off egr, all of the emissions crap. the computer has capability of controlling an electric fan with high and low speeds. in my opinion this option is better than getting a dyno tune. go to eectuning.org and read the faq section.
