Dinan S2 leaves almost 20whp on the table!

10 Aug Dinan S2 leaves almost 20whp on the table!

Yesterday I was going some online marketing and my boss came in and told me that an M6 was coming in for a dyno and that I would have to pretty much handle it all, cleaned up a little a bit and the dyno ready when the Dinan S2 M6 arrived with a tasteful amount of mods installed from Dinan. Met with the owner, tossed the car on the dyno and started going down the list.

Basically it was a complete S2 package, for those who aren’t familiar with that package this is what it includes:

Stage 3 Engine Software; Free Flow Exhaust; High Flow Air Mass Meter/Intake Assemblies; High Flow Throttle Bodies; Under Drive Pulley; Stage 2 Suspension System; Carbon Fiber Front Strut and Rear Shock Braces; 3.91 Limited Slip Differential

After a few pulls on the dyno myself and the owner were not too satisfied with the AFR’s the car was showing, we ran through some ideas and I informed the customer of the special we are having for the Chicago tuning event coming up here in two weeks. The pricing is limited to the event only but we figured we could make an exception for this situation!

I’ll have some images up of the car later today but here is the graph:

This was after about 8 files back and fourth for a few hours and we still think we can improve the mid range a bit so when Jeremy gets out here in about a week and a half we will try to get the M6 back on the dyno!

All runs were to the increased rev limiter of 8,400rpm, the before graphs show me letting off at 7,800 because the tach signal was slightly off. We didn’t fix the tach signal until a few tunes in which is why you see the difference.

Please e-mail me at [email protected] if you have any questions about the tune or any other tunes, check out this blog post with details on the tuning event in two weeks:
