first ill start with an answer to the original post, Fordchip.com rffperformance.com and reinhartperformance.com all use the same programs that were written by the fordchip guys. all of them work. in my case on my stock 96 tbird i was running 15.7 all day, a new chip from fordchip.com and i was now running 15.00 all day with a best of 14.97, ive since put a 2000 4.6L into the car and a reflashed eec but winter in chicago makes it hard to go to the track so no new numbers yet.

anyway,

superchips vs diablo/autologic = 1 bank vs 4bank, what that means is the superchip blankes can only modify files in one of the banks in the eec, a diablo can modify files in 4 banks, ie 4x the amount of stuff. for instance, a one bank superchip can not change fan start/stop function, where a diablo can access the bank where the fan controls are located, so with a 4bank chip i can now program the eec to turn the fan on/off at different times. there is a LOT of other things that a 4 bank chip can control where a 1 bank cannot.

dynotune vs mailorder: a dynotune is by far the best you can do, no question, but if you dont have access to a dyno mailorder is your only option. the websites mentioned above do use diablo blanks, ie the get unprogramed chips and then reprogram them with thier programs. when you order from them you need your box code, and mods to your car, they take thoes mods and program a custom chip programed for you and your car, they actually program it, not just download something like what diablo does. they custom calibrate a chip for you.

timing, its best done in the eec not the timing adjuster, then again i do it with a octain spout.by using the eec timing is adjusted through the curve, this is best done on a dyno that way it can be adjusted and fine tuned but it can be done via mailorder, they have thousands of dynotunes under their belt and they have probably done many cars with the same mods and they can get something really close and still have it a safe tune.

ask diablo/superchip/ape/autologic what an octaine spout is, then ask them how they use it to help in peformance, i bet you they wont have a clue how to use it to gain performance, then go to fordchip/rff/reinhart and ask them about it. they will tell you what it is and how to use it.

lastly, superchips blanks do not work well on 99+ eec, they changed the actual computer board it is a little thiner and the superchips blanks dont seat that well on the board. they work but ive seen problems with them, thats why fordchip started using diablo blanks.
