Just put 5 miles on my stage 2 VFJohn tune...............<insert big grins here>

My impression of stock muffler with Johns Stage 2 tune. WOW, much better mid range throttle response. More peaky power. PULLS MUCH HARDER .Breaks the tires loose much more easily. Sorta like on a 2 stroke machine when it comes on the pipe. Def more of a "hit" of power in the mid range. I'm impressed. THANK YOU JOHN. ZERO REGRETS. I bought a 2nd stock muffler and removed the cat, but haven't installed it yet. So it should pull even more now that it'll breath better . did I say WOW WOW WOW!!! I'm not saying it's ludicrous gains, but def does push you back in the seat more and roosts the tires.

Without the cat, do you think you'll need to retune it to get the A/F ratio right?

I did Graves tune and full exhaust system. Definitely added some lower end torque and a ton of bark, it feels more powerful from the hole and out of turns, but no difference on top speed, the problem with the top speed is the clutch. Mid range seems to pull harder, but the stock clutch keeps the rpms so high its not as much of a difference as I hoped but I think a clutch kit would change a lot. Haven't noticed anything with gas mileage but I'd imagine I'm not getting better mpgs lol.

So how did it do with the VF Stage 2 tune and the catless muffler??
