@Maxense it isn’t that bad, mainly a tiny gain in torque in low range, slight decrease in top range in both power and torque. A re-tune and a hi-flow air filter would result in decent gains, I would think. Of course, I just ordered my Lv10 and De-cat today, so I am probably making a self-serving justification LOL. Once I receive and install, I’ll do a proper soundcheck, flybys, revs, and idles vs the stock setup because as-of-now I have yet to see one. However OP’S video has convinced me enough to buy the kit.
Sorry the Leo-Vince Dyno is a screenshot, wouldn’t let me upload a PDF.
