It feels as though it wants to pull all the time. But I'm finding out that when I'm cruising through town in 2nd or 3rd gear (depending on posted speed limits) around 2500 rpm's it's pretty smooth and cruises right along. On the highway I can be in 5th or 6th gear running 70 to 75 mph and it will pull up to passing speeds with ease. Very Nice. Lifter noise can be a little noisy but tolerable.

hows 58 mm throttle body at low rpms
I have close to a stage 4 , mva heads, power duels, monster rounds, sepst to tune it. still racking up the 1000mile break in , have about 600 miles on it now.
wondering it there is any flat spots at low rpms with larger throttle body. I have the same pistons as stage 4 kit in mine. I have 255 cams though so hp should be a bit lower and expect torque may be about the same as woods cam.
I still have the stock throttle body, may have to wait for 58mm one blew about 3000 bucks this winter on all the parts. how do the lifters sound, my 255 as expected are pretty loud even setting them at .130 after preload. do you still have stock lifter in yours

The throttle body seems fine. I was a little concerned that it might be to big but it is working good. As for lifter noise it has a bit of chatter but not bad. The lifters are new stock harley hydraulic. Good luck with yours I'm sure you will like it.

I will try not to miss anything, Heads, Piston/rings, Cams, SE Tuner,TB,injectors,Clutch spring,Push rods. I exchanged SE tuner for TTS tuner, Cams for Woods 400's and Push Rods for SE adj. push rods. I also added SE roller rockers, oil cooler and ACR's .
