I ordered JB4 and the BMS clutch stop last week and got around to installing both this weekend. Very happy with both products! I even found a little surprise while installing JB4 that you can read about on my blog, just click
here.
Filled up with a mix of 93 octane and E85 and was amazed on map 5! There is no traction until 3rd gear...
If you're on the fence about purchasing JB4... just do it! So worth it.
