Help with mods that actually give HP gains??

[Woody54]

i've been checking the FS threads and MP3 ecu's rarely come up for sale. where is the best/cheapest place to obtain one? (either new or used, cause i'm not totally sold on the flashing thing)

Personally, I took a shot in the dark and located a few with Partsfinder.com...which is a salvage website....Most of the replies were bogus and automatic, but got a couple that actually had the MP3 ECU...Cost about $300, but got it in 2 days....Search by using the actual part numbers and any of the three production runs will work in any manual 3rd Gen Proto...

$300 is a lot to spend on just an ECU...hell my old car got a full custom tune/emission codes erased/raised shift points/etc for that much.

In an otherwise stock car, what are the advantages of putting in an MP3 ECU?

**Advantages are advanced timing using high octane fuel causing a bump in horsepower....Most significant difference is a smoothing of the power band, which creates a seamless delivery of power...unlike the stock P5 ECU which has terrible peaks and valleys in the curve....
