Tuning Advice .. Please
Probably been asked a million times but I cant get the search thing to work......
 \\;
Do you need to adjust any electronic mapping etc etc if you are fitting a Big sucker air filter and slip on pipes ? Fat Bob is the bike and don't want to change the header pipes just want it to breathe better run smoother and sound better.
 \\;
Oh forgot to mention I fitted the Xied's today but not run her yet.
 \\;
Thanks for the patience !!

If you change the intake (increase) \\;you should get a stage 1 download, at least, even with the Xied's because the Xied's are not going to affect your AFR at WOT.

I've heard the dealer installed download is a wast of $$$$$$$$.
I'm running a Fule Pack. After installing the AC, pipes and fule manager I changed to the quiet baffels &\\; was able to change the AF ratio setting in my own garage, in 5 minuets and for free!

It's not a Buick, it's a Harley - haha. \\;

Since you have the IED's, you may only need a stage 1 download but you need at least that at a minimum. \\; I've seen people report good results with that combination. \\; Bottom line, you need to do something more because of the high flow a/c than the pipes/mufflers. \\; There are many other options of course, i.e. fuelpak, T-Max, SERT, PCIII, etc. \\; But yes you need something more than what you have.

RE: Tuning Advice .. Please
If you buy a matched set of intake and exhaust its the only way to know if you have to re-map and what level you, otherwise you need to Dyno it.
I bought the S&\\;S low restriction intake and slip-on pipes which the stock ECM can adjust for to keep the same air/fuel ratio and emissions as stock.
