Maybe you need to install the thunder mfg intake gasket . These nike are notorious for intake leaks. Send a PM to Almsy here on the forum. He has a cobra power pro and seems to like it. I have a PCV and it is great and cheaper than the power pro.

hi
I have the "cobra tri oval" built on my VN1700 Voyager. I left everything else original.
the "cobra tri oval" were insulated with insulating wool. so the system has a good sound is not too loud, and not take away from popping the gas.
to the Irish pop to minimal. You can also use the bulging sheet metal absorber tube a. that helps.

greeting

I have the Tri-Ovals, thunder air kit, and cobra power pro - Yeah she pops on decel, but not too bad - generally only if I really let off of it - If I ease it down there isn't too much - My last bike popeed like a movie theater popcorn popper, so I'm OK with this . . .

Got the Cobra Tri-Ovals, PCv, Thunder Tornado Air Kit on my 2011 Vaquero, and it only pops on hard deceleration at 2100 rpm, if I decelerate slow, no pop!

I have V&H slip ons. I had a PCV on and switched to a power pro. I get a little but noticably less popping and better gas mileage also seems better acceleration. Can't go wrong with the power pro.

I'm running 87 octane now and idle up . seems to slow down the popping , but is spending 434.00 on amzon for the powerpro worth it if you still got the popping?

The purpose of the auto tune is to correct the lean air/fuel mixture, which will improve performance, not to eliminate backfiring. When I spoke to someone at cobra he was very adamant about that issue. He seemed irritated that I even brought it up, even though the box says "virtually eliminates backfiring on deceleration". On the other hand, it does cut down on backfiring on decel so it does help.
