This M20 E30 325  came in with Stage 3 Modifications, all we had to do is tune it.    difficult with a dying TPS

My E30 323 supposedly has a 2.7 low compression motor in it

Run 3 is actually run 2 after we modified the exhaust with an X-piece for more torque
Run 2 is the final run done yesterday after my MAF conversion and tuning that using the Unichip

E36 BMW M3 blew a tyre on my Dyno mid 2011, when the before run was made.
So obviously something has changed on the vehicle since then, as a Unichip is unlikely to increase the power this much.
