Have an 05 FLHT w/ SE 203 cams, Ness Big Sucker and Rinhart TD's. Have gone back n forth about getting a 2 into 1, but that's another story. Anyhow, I still want more power, but really don't want to bore it out to 95, don'yt have the cash, and kinda wanna see what I can do w/ 88. My bike is carbed as well. Is an ignition the answer. Screamin Eagle, Crane etc. I think between cams, pipes breather, maybe a carb upgrade and ignition I may be able to get some pretty decent power. Any other suggestions besides more displacement.

 

Save your money for a good 95 kit. Ignition aint gonna do nuttin for stock compression.

 

There's no substitute for power other than cubic inches. A higher lift cam will give you more power such as a 257cam and will work well when you do decide to bump to a 95 you can also port and polish your heads and get a significant increase

 

What BAGGERDSM said.
In order to get more power from an 88", then cams/headwork would be in order.
You can easily see 90 hp and over 100 ft/lbs. of torque, or more, with the proper set up. Trouble is, that is not .59 cents.
At that point, you could/would need an ignition.
Also, the 257 S/E cam is NOT a good choice in those OE 88", as in no way, can enough compression be established to support it, and IF there was, the power would be waaaaaaaay over to the right of the chart, and be a genuine turd in the normal riding range, as are the 95" set-up's, with those cams, from most dealership level builds.
