Hey guys, I've got a '95 M3 I'm bringing back to life. Currently in the process of doing all of the body work and taking care of any rust issues, then doing suspension upgrades afterwards. I'm in search of help with the tuning of the S50 engine. From what I've read on the forum, these engines can handle a lot more and are very de-tuned from the factory. My plan is to do an OEM rebuild on the engine (gaskets, bearings, seals, VANOS rebuild, maybe some machine work to deck the head, etc.), and I would like to tune it out as much as possible with a quality tune. If that means upgrading injectors or other things as well to accompany it, I'm fine with that. Not really looking to do upgraded cams or any serious engine internals. All advice and tips are much appreciated. Thanks.
Look at Turners Stage Three kit for the E36 S50.

I think tuning evolves and that old Turner stage 3 shark injector tune probably has not been touched in 10 years. It’s not a bad choice but would not be my first choice today.
Ok. But it’s still old tuning that probably has not been updated in a decade. Turner used Conforti mostly, who was very good, and also used Karl at AA, who was also good. But I don’t think the tuning was touched after Turner came out with those staged kits.

I have heard that Confoti tunes for 1995M3 can run a little lean depending the octagon rating of premium fuel in your area of the country.

Our top-of-the-line engine upgrade for the 1995 M3 produces and additional 57 horsepower! An aFE Cold-Air Intake with larger European mass air sensor, Schrick camshafts, "24lb" fuel injectors, and a specially-calibrated performance chip deliver extraordinary output. Many people have tried to copy this kit but no one has perfected it like Turner Motorsport

The M3R would have been based on the Euro M3, which used a different engine than the OP’s USA M3.
OP,
You should look no further than 22RPD.com for your OBD1 tuning needs. He can do a chip for your specific build that will be very close to optimal and perform some refinements that will get you very close to perfect without much fuss. I've worked with Zack in the past for my built M50 3.0l build and he made the process effortless.
