Tuners are only as good as the map you load. If you've added a quality tuner, and didn't gain solid performance, you don't have a good map for your bike. Fact.
Ok, I agree, with a quality tuner and a good map you'll see gains but I think we have a different perception of ''gain solid performance'' on an intake / exhaust set-up.
And besides eventual performance gains wouldn't you agree that running an intake / exhaust on stock EFI is still safe technically speaking?
Mnnthbx Half these guys that shit falls on def ears... Proper fuel management is Key No matter what any of these Grommers say. Shit even if all someone did was put fuel management and auto-tuner no other mods could tune the shit out of it to see gains... FACT! lol
No one in this thread said that proper fuel management is not important, I agree it is crucial on a heavily modded machine. It's just as important on a stock Grom and thankfully Honda did a descent job on the Grom. The EFI system works pretty well, is cheap, simple, reliable and easy to diagnose.
Brian was basically asking if he can run his Grom with minor mods without a controller of some sort or not. Answer is yes yes. DOUBLE FACT! lol
