Another poorly chosen configuration brought this Screamin Eagle 120R in to Protech for tuning.

This owner originally came in after having a 120R motor fitted elsewhere and wanted a good tune. We carried out the tune and he could not believe how much better the bike went, as he said “just from a dyno tune”

We always recommend the most suitable exhaust, and after years of tuning, understand which system works best for any configuration from having the data on hand.

Use D&D exhaust systems, they work! After a re-tune the bike was substantially better. We handed the motorcycle back with the power he had been expecting from the beginning from such an inexpensive upgrade, which was carried out elsewhere.

Correct tuning is paramount for engine life and should be carried out before collecting your bike from the dealer after any upgrades.
