Have a 2013 CVO King with the 110. Current mods are Drago 580 cams, SE high flow air cleaner, Dragula 2 exhaust and SE race tuner. Question is has anyone with similar mods went to a 58mm tb and 5.3 injectors? If so what kind of gains if any did you see. My builder is saying it would suffer a lil loss in torque between 2k and 2500 but would have gains in the mid and high end. Please advise IF you actually have done this swap. Thanks.

 

Never swapped your combo but based on the hp this combo would make the injectors are definitely overkill and the 58 may see a couple at higher rpm but would lose in the lower and even I bet mid range based on side by sides I've seen. Basically unless you add headwork this upgrade is not worth it at all. IMO

 

 

I looked into going with the 58mm as well when I did my 110" build with cams and headwork. Not needed. The TTS software I'm running tells me I'm fine with the stock one.
