I think for the kit itself without the computer was about $276. I think with the computer is about $490.
well around here the custom tune is $450-500 and that includes dyno time and the 2 setting flip chip (were you can have 2 sep. tunes. ie. one for N/A and one for n2o), from the guy you may have seen in the mags that did the eaton porting called APTEN. now how is that ever going to not beat out the a9 family of processor? You have a custom fuel/spark setup for YOUR combo, You get 100% drivability/gas milage/smog legal, and the power will be more than that of any stock processor.
Now stock for stock the a9 family is better and less prone to mod issues. Now having a modded engine say with a H/C/I that is preaty common even with just one of the 3 any stock processor tune will be off and not optimal so your stock processor is still not as good as a tune as a custom/ self tuned deal. Even with the "bad" 94-95 processors once you change the bad things, and you can or the tuner can, your taking all the "reasons" out of the a9 swap.
Bottom line is your going to spend a good bit of money, either you will have a
1. stock ecu with self tuner = you can change as you change your setup
2. stock ecu with custom tune = you should wait until your done with the mods so you dont have to get it re-done.
3. stock a9 swap = a stock ecu and if you plan on modding more you will run into that ecu's wall and need to get it tuned (if your not already), and no matter what you will have spent you will still need a tune of some kind to get the most out of it even if your alittle bit modded.
The whole a9 swap was the only option for the SD/94-95 guys back in the early 90's and there were no tuners/self tuners that gave you access to the ecu's tables. That was also the case as the 94-95 ecu was around before the tuners were around, its just a old bandaid fix.
