Computer Question for 800+HP

At the motor I'm hopeing to get 800+hp. I have seen other cars in mags with the same set up I'll have with one thing diffrent here where I have something diffrent there and they are making in the 900's, but I'm not going to get my hopes up that high.
I'm trying to get an idea as to what kind of computer system I should run with stock cpu or stand alone. I do want goo driveability on the street and to pass inspection,hopefully.
Any comments will help so much! Thanks guys!
 
Why do you want a new ECU? Not that it's a bad thing to do but it is expensive. MOTEC M48 is a very nice unit but at $3k its kinda painful. What engine? Its not the one in your sig. Thats for sure. What ever engine it is get 3. You will be going through them in a short time.
 
Sorry never changed my sig, there is the new one. I'm sure the motor will handle it. I'm going to start with about 17lbs, then work my way up if there is any room to work with.
I want a new ECU or piggy back because I'm not sure if the stock ECU will run the S/C and the motor with all the diffrent specs.
 
+1 stock ecu and some ignition system like boost a spark or something of the sort

the stock ecu has been reliable on high hp cars plus if you want to pass inspection, theres no stand alone that im aware of that will be able to support the obd2 inspection system
