Help from the pros about engine mods
Just bought a SG. Put a PCIII big sucker and rianhart true duals on. runs good BUT ! Im not happy with the power. I know. theres lots of stages and kits , but I WANT TORQUE AND POWER . I own a bigdog chopper with a 117 S&S engine XXX carb 600 cam. Yep it will run. I would like for my Harley to be compairable to the S&S . Can i get a screaming eagle 113 kit for my Harley ? I guess the question should be , Which is the best way to go on this. Many of you pros have traveled down the road i want to go on and it would be great to here your opinion.
Thanks.

GMR Performance sells a nice kit....Headquarters sells a nice kit...Mike Roland has a nice kit with the Kuryakyn Wild Thing line....point is, do some research and buy a proven kit, dont cob together parts...ditch the PCIII for a DTT tho...how much you got to spend

Its a Daytona Twintech.... it replaces the stock ECM and is a closed loop EFI system. Self learning/tuning and no more dyno runs.
I'm ordering one for my bike but I havent figured out a build yet... So ill let you all know how that works out at this stage and as I do the build and it learns the new stuff....

RE: Help from the pros about engine mods
Yep, Bryans on the money as far as getting a good tuner when doing the build. Just finishing mine up and went with his and Phils input, although I did run a PCIII on my other bike and it was pretty darn good, but the guy running the dyno was excellent. You get a hack running the dyno and no matter what open loop tuner you run, you got issues, plus dyno costs.
As far as the build, another one to look at is Woods Cams and they do have some packages and recommendations also. Some guys like to stick with mostly HD parts ( I have heads and pistons) but only after talking with Woods to see what combo works best with his cams. GMR and Headquarters are good, don't know much yet about Kuryakyns Wild Thing setups.
Bottom line, ask, talk, read before spending your hard earned money.

RE: Help from the pros about engine mods
The DTT is the Daytona Sensors Twin Tec Tuner which allows you to adjust fuel deliveryvia your Delphi EFI system. You can tune it yourselfand you can order their system with the TCFI Control Module which includes anauto tunemode which is pretty slick. Options include theWego II wide band air/fuel metering system which allows you to strap on an exhaust analysis kit to measure your air /fuel mixture as it comes out of the exhaust. It's pretty pricey stuff butworks very well if you have the aptittude to tune fuel injection yourself. One warning about the DTT, you must be computer savy and have a good understanding of mapping and data logging in order for it to be effective. You'll also need a laptop and should have the ability to re-terminate wires within your harness.
I learned a lot about this product when another Sportster owner I know got into their system to tweak a stage II 1200. It's time consuming, but very rewarding if you like to play with this sort of stuff.He was working close with Chris at Daytona Tech to create some maps for the 1200. If you want to know more about the Daytona Sensor Products, click on the links above. If you need a link to some do it yourself photo's, email or pm me and i'll send you some links to more info on the installation. Hope that helps you out.
