HI, we just finished a build on a 2016 RGS 103 ci we used a HD # 92500005 stage 4 SE
CNC ported Factory cylinder heads
10.5 to 1 forged pistons
SE-259E cams
pushrods
58mm throttle body
Hi flow injectors
New cylinders
It was installed by a very knowledgeable and professional builder we have not started it up yet. In the injector box there was a WARNING saying DO NOT start up UNTIL the ECM is re calibrated by the dealer or damage to engine and ACRs will result.
I am now running a FP3 and have a SE Tuner came with the kit
Can I start the bike without hurting the ACRs or engine I believe there worried about fuel management more the hurting the ACRs
I'm looking just to break new engine parts and send to dyno with Dynos choice of tuners thanks

wasn't sure were to post this so I posted it twice

 

I'd ask the builder who installed the parts.

 

Since you have changed th einjectors and Cam I would recommend returning the ECM to stock (remove FP3) then install the SE tuner and base calibration for your parts. You should still get it tuned later but that would be the safest way with the parts you have.
