I notice the SE 103 stage 4 is 10.5:1 with 58 mm TB  and 5.3 inj. Has anybody had experience with this kit?

i was concerned about TB and inj overkill. 

Does the map supplied with he sure tuner work? 

Hi,

I think the injectors are 4.9 and the throttle body works fine, no map on SE tuner for the pro race kit i believe only the street kit

Think alot of people use a 110ci map
Thanks

I had the stage 4 kit, it was ok, until I had the heads ported, swapped SE259 cam for a t man 625 cam, now it pulls like a train. 110TQ115HP. torque is 100 at 2500rpm and 110 at 3200rpm through to 6000rpm. never had a problem with the T/B, I wasn't sure of it either, at first.

Giday Ash, How ya been? Have my heads at Troy now looking forward to getting them back. He has done a few sets now and they are making the numbers

I'm happy with mine, softail and puts down 108 & 108 standard stage 4 with V&H Long shots

Had the kit in my fatboy got 109/110 no problems very happy  , put one in my 2014 fatbob feels very good , yet to get it dynoed
