Has anyone tried installing aftermarket exhaust systems along with the fuel tuning? I’ve heard it can make a big difference in exhaust flow and overall performance.

I did this, and wow! The bike feels more responsive, and the sound is amazing. Just be sure to retune afterward.

It’s crucial to make adjustments based on your riding conditions. If you’re mostly in the mountains, tweaking altitude settings on your ECU can help a lot.

Great point! I always make sure to recalibrate after big trips; different terrains totally affect how the fuel is delivered.

Remember, tuning is a process. Don’t expect perfect results on the first try. Take your time to find the right setup for your bike.

Totally agree! Plus, it’s a good excuse to take your bike out for testing rides!

What’s everyone’s opinion on the best aftermarket parts to start with? I’m looking for cost-effective options that yield noticeable improvements.

I’d say a good fuel tuner is a must. It’s worth investing in quality parts that can really elevate your riding experience.

Just remember, tweaking performance can sometimes lead to a decrease in reliability. It’s all about balance!
