Get rid of the LC3 plug - it’s a hot plug. You want a medium heat plug. O’Donnell’s purple medium long reach or a McCoy MC8 are good medium plugs. A Novarossi C6S or C6G is a great plug too.
Next, I’d drop the Traxxas pipe and get a better pipe. If you have the high rpm dual chamber resonator, you’re good for the most part. Just drill the stinger out. If it’s the single chamber, get the two-chamber at the very least.
Lastly, change your spur gear or clutchbell - the spur gear is the cheaper option. Try a smaller clutchbell or bigger spur gear.
If your truck is setup the same as the others you’ve seen and yours isn’t doing what theirs does, then your tuning isn’t right.
