Problem with low top end

Have you checked your driveshaft bearing?

I have a 2018 50th, 137, studded Winder.
This sled has a Precision EFI 230 tune, TP holeshot helix, TP springs, 911 clutch cover. Secondary spring is on 3 and 1 and the primary weights are set as per TP. On the weekend my buddy’s STOCK winder had no problem keeping up with me. I am seeing a max speed of 172 km/hr (106.7 mph). Any thoughts?

There are some great suggestions here, however I like to think outside the box and will add my 5 cents here:

You state you are running PPE 230hp and experiencing low topend. I would suggest you call PPE and upgrade to stage 4, which is 320hp. I would be willing to bet this would help topend tremendously!!
