Default Dealer installed Stage II

I'm having a Stage II upgrade installed by the dealer and the Dyno is listed as a line item. My question is: Does the dealer provide two dyno reports? One before and one after?

Depends on the dealer- If anyone asked for a stock pull, most would do it for them, but since most stock bikes are within 2-3% of each other, they should be able to show you what a typical similar model makes in all stock condition.

2018 FLHTK (SE AC, V&H Power Chamber Duals, V&H Twin Slash Rounds) wanted a little more- Swap from SE447 TQ cam (red run) to TTS100 (blue run).

Hi all,

Posting in here also due to the number of tuners on the thread.

Had some serious power issues with my bike both pre & post installing the below parts. After some suggestions being pipes, sumping and some other things we've got it in with dynojet today to discover a limit/restriction applied to the throttle somewhere.
images below may tell the story better to the trained eye however DJ have said that when the throttle is opened to 100 (2nd row from bottom of table) the blade is maxed out at 26.

Going through their PV settings they could not find a way to change the value (2nd row from top in the table) or even see a limiter on the throttle position. Stock 107 map loaded along with another 124 map and still no success. Its as if it can't be flashed off even temporarily.

DJ have also said that a replacement ECM would not fix this (I don't understand why but appreciate them saving me the best part of Ł1000).

To be clear, the bike was bought 2nd hand as a stage 1 107 and it had power issues then. DJ have said that the TPS is functioning in the new SE TB as its registering the data on their PV.

Left the bike with them and awaiting a response from dynojet USA for assistance, but there's no guarantee that it can be solved by them, so trying to reach out ad much as possible.

Upgrades:
SS 128ci kit (put onto 107 stock motor)
SE 64MM TB
Fueling HP+ 465 cam
6.1gs injectors
SE high flow filter
V&H short shots

Any help, suggestions or wisdom is massively appreciated on how to remove or change this limit.

I'll ask about the compression based on the above to see if any red flags arise.
