You can't compare MSD TL to EPIC....
Now if your looking at the ATP Flame vs the MSD TL, MSD TL Has more (Hotter) spark, makes more power... I tested the FLAME & MSD back to Back on the same motor, same everything.... Night & Day you can't compare the two...
Now if you ride saltwater the ATP flame is the way to go since its in the oem e box. I ran the Flame for 1 yr so I know how it works
Epic vs MSD Enh... Yes your motor will make more power with the EPIC, Spark is the same between both by visual.. but to date I dont have one buddy that has one that runs perfect every time... 2 buddies have XS865's, running Epic's, had start issues, fighting itself to start, etc. Both have blown motors (OEM CRANKS failed, low time motor)
Hard to beat the MSD Enh, advance the stator 2-3 deg & it hits hard, starts & runs every time, no hard starts....
The problem with our sport is you never see true reports... First true ride report I seen on a hull was Ross on the Bob... I guess I'll be the dick here & make this post
Chris is a great guy to deal with, I think in due time all the bugs will be worked out in the Epic/Flame..
