Been looking at Xieds before fitting the fuel pack but because I added pipes and a filter thought that I need more than just Xieds.

I have been informed that Xieds and the Fuel pack work on different systems one close loop other open loop and because of this they compliment each other.

Has anyone fitted both because I would very much appreciate you views on gains/losses and if Xieds are worth fitting with a fuel Pack

 

I have tried both at once, and here is my opinion on it.

Just use the xieds and you'll be fine. When i had both on my bike ran like crap. Also, I'm pretty sure that if you just have the xieds on the closed loop portion the ECM will re-adjust the open loop after 10 minutes and will enrichen it based on the closed loop usage.

 

If you have no intention of doing further engine mods, I'd agree and say save the money and only run the XIEDs. If you plan to do anything else, save your money on the fuelpak and just buy a PC V now.

 

It's been my experience that the XIEDs will work fine on their own. However, I've opted for cams...so I'm going with the TTS as that's my Indy's favorite.
Btw...I can save you some bucks on the XIEDs if interested. (Forgive me Lord for the shameless plug, and bless the starving pigmys in Africa.)

 

I have the fuel pack already fitted

 

I think this is a bordom thing.

Is the PComander better than the FP and is it easy to fit and programm.
Also my FP is a very tight fit under the seat where will the PC go on my Fatty with a mustang seat
