Long story short, my local tuner royally screwed me over with my MSS54 to MSS54HP conversion to where I had to cancel my dyno appointment with them because I didn’t have my DME back yet. I finally got my DME back and it doesn’t seem like my tuner cares to make me a priority so I NEED a good, safe tune to put in this thing. It’s an S54 swapped E36 M3 stage rally car and I am supposed to be leaving next Tuesday for our next rally… who can I trust?
Simple setup, basically a stock rebuilt S54 (.5mm over), Geoff Steele CSL box, headers, stock section 1, factory section 2 until around the axles. Ran it for a season on the stock intake setup and am now going CSL.
