1200 w/ Short Shots: Decel Pop, no Remap
Just looking for other people who have installed V&H Short Shots and their experience with the pipes with no remap. I'm scheduled to have the download by end of the week, but curious if others had a ton of decel popping.
Checked for a leak, doesn't seem to have one. Replaced the crush gaskets with new SE gaskets.

Do not waste your money on the hd remap it still runs way to lean. Buy a tuner even if you get something cheap lole a fuel pak or xieds you will be better off. I run short shots with a v&h fuelpak and I get some occasional decel popping. It really seems to depend on the weather and fuel quality at the time. But it's not that bad.

With the Screaming Eagle air intake and 1000K dino done, I still get decel popping. I like it b/c on occasion it scares the crap out of other motorists. HD said they could richen it up if I wanted, but I would loose some performance.

The download reduced the popping, and even though some say it's a waste I wanted to advance the timing a bit and up the rev limiter which XIED's alone wouldn't have done. I'll probably still add those and settle on the download+XIED's for my "Stage 1" ECM upgrade.
I've never been a fan of piggyback systems and have seen more than one computer fried because of them. Not on HD's specifically but plenty of cars.

How would getting it tuned the right way make you lose performance

Don't necessarily think that's a line of BS. You can tune an engine for optimum performance and still have popping in the exhaust. This is due to a A/F condition in the exhaust after it leaves the cylinders, not the running conditions in the engine. With extremely short/open pipes like the Short Shots this is pretty common.
If they richen it enough to "flood" the exhaust with fuel it will reduce popping but the engine may not perform as well. Just my experience with race cars.

I was more curious as to what you meant and worded it wrong

I have Short shots, V&H fuelpak and stage 1. I had decel pop and was growing tired of it. It wasn't bad but with a short pipe I think it hard to completely get rid of it no matter what direction you go. I took the bike in for inspection to a local custom shop. They sold V&H as well as Power Commander products full line. The Mechanic sold me on Star Tron fuel additive and said run 89 octane. Reason being most gas stations have 93 with 10% ethanol here and how much do they actually sell at 50cents more a gallon sitting in 10k tanks. After a little chemistry class i bought into it, he could have milked me for a grand with a tuner and dyno. Within the first 20miles into a fresh tank with the additive the popping was damn near eliminated and when it did was a low sound and not repetitive. With 2 tanks in I'm sold n my mpg went up by 5 and I'm riding it no different. Look into it and give a shot. It will pop though when the engines cold but when its up to temp you'll hear the difference.
