Pretty much. Watch the needle, every time it bumps counts as one stroke. Like I said, I've only seen the reading taken with three compression strokes. It should show around 190 psi on the gauge. Some reading material if you have not already came across it. It will help you try to narrow down the cause.

Yeah it's a little high, but it pulls from the bottom all the way to the top. I should change the cams but it just runs so good now. I do mix race gas with the pump fuel in the real hot days as todays gas is real bad. All we have here is 10% ethanol gas and it's not the same everytime it can range from 0-10% and swear it is more too. I run mine only on maps the O2 sensors just plug the pipe the ECM just needs to see them there to keep the light off.

Very true, it could be better set up. I've been friggin around with the timing and I'm getting close. It's hard because I haven't had much time for good test ridding, but every time I take the bike out, I pay attention to where it pings, and pull a bit of timing. I only get it now just as I roll on, so I'm thinking about 20% throttle. Anyways, I hope to get a compression test done soon, and might end up changing cams down the road, but for now I'll try to get rid of the ping, even if it costs some performance because I have a big trip coming up in early june and don't want to be trying to tune in a new cam at the last minute. Wish me luck, I'll post back in a few days with my results.

I've noticed that this forum does not have a sub forum for everyone to load their map files with a description of mods, unless I have missed it, and I have always wondered why.

When I bought my bike In 07, the Pc's and others tuners were out there, But this is one of the prime reasons I went with the SERT. I didn't have to have to keep tuning and tweaking my bike.
NOt to throw stone but Ur having Soooo much problems getting U bike dialed in..
and U just keep messing with it trying to get her right..
This just adds to my being feeling of choosing the right tuner in the get go..
I haven't had a single issue or problem since they install the SERT and dynoed it.
Mostly cause I didn't want to have to keep messing with the tuner..
I had enough of working on my bikes back in 72 when I bought a new 71 AMF Harley that I had to tear down every Yr just to keep her running..
This is by no means to bad mouth anyone or anything.
Just to say I am totally happy with what I've got and glad I went with the choice I made..
I still hope U get Ur bike running as it should with what mods U've done to her.

A SERT is all fine and dandy. When you start getting into heavy engine upgrades such as big bore kits and ported & polished heads nothing can beat a tuner such as a Dynojet or Thunder-Max. The problem is the combo he has chose to run. The 103" with 255 cams has had more pinging issues than any other combo that I know of. A PCV w/AutoTune dialed in on a Dynojet Dynamometer by a certified Tech that has been thru the DynoJet training course will hands down give you the best tune available.
