    they are pretty much the same thing.

    pr4's came in late 2nd gen tegs that were obd1 b18a's and soem 94 b18b's.
    they ar epretty much identical

    Maybe he's just a better driver. No offense, but if you both have the same swap and you have more "performance" persay than you should be pulling on him.

    I used the stock DX ECU for the longest time then I got a PR4, when I finally got the P75 it didn't make that much of a difference.

    It's a very minimal power difference. I'd say at most 5 hp difference. Check the compression that should be first, then work from there.
