I am looking to buy a stage 1 tune for the X5 50i that I recently picked up. However, I have seen other tunes that pick up a lot more torque on pump gas, just just Jb4 piggybacks. Are the dynos posted in the N63 info thread pretty accurate? I would love to get a 100 ft-lb torque increase, and would rather not go to a Stage 3+ to do it, I want an easy install and easy removal.. I plan to only run pump gas Woodland Hills 91 octane to be exact... Thanks!

We'd suggest the Stage1 tune. gains are around 40whp / 50wtq. The N63 platform is not great for tuning so take and enjoy the easy gains.

Thanks. Sounds like a plan! Would you surmise that tunes like dinan with 580 ft lbs are probably lying? Jb4 stage 1 offers a lot more value for sure.

Yes, nonsense. Plenty of videos of Stage1 vs. Dinan races floating around. It's not even close.
