V force John tune
Received my CPU ( Tune #2 ) back from V Force John yesterday, I took my UTV out after installing the CPU and the recommended Empire Exhaust that V Force John recommended, then did a thorough test on it,
all I can say is( Holy SHIT ) WOW WOW WOW, I knew I was going to get a performance increase but I was not ready for what I got this thing literally set you back in the seat not only with instant throttle response but in mid range and then when it goes to the high RPM range it’s like a whole Nother animal up there,
This is got to be one of the most impressive tunes on the market, thank you very much for the TUNE John you did an outstanding job on this tune.

How critical is the recommended exhaust? The reason I ask is the Empire is a little flashy to me. I am partial to the MBRP exhaust.

I see they have a single and a dual. I guess the single is not bad looking and I could deal with that one. Can you advise on what one he recommends?

I was wondering the same thing and i agree, the dual Empire is a little flashy. I kinda like the look of the Evo but haven't heard to many sound clips of it.

That would be a question for V force John but if you’re looking for less flashy they also make the empire exhaust in black.

It was recommended because with the quiet cores in the Dooleys you don’t lose any performance were in a single you’ll lose a little performance with a quiet core.

You don’t have to do the aftermarket exhaust... stock muffler can be ran in ether configuration with the cat gutted or not. Mid and low range is where you’ll see your best gains. It’s totally worth the $250!

NOTE... if you run the stage 2 tune you’ll need to run premium fuel. Low power mode in the S2 tune will pull timing in case you only have 87 this change does away with the throttle restrictions.
