Advice on tuning bits fitted to my bike

[Boyd1005]

Looking for input from the knowledgeable folk.
Just picked up a mint 2012 S10 with the following aftermarket tuning bits
Motad S/S Silencer with stock headers
Off the Road.de stickered ECU - so presumably flashed????
Powercommander V with O2 Optimizer - but I have no idea what map is loaded to it
K&N Air Filter
Lambda sensors still fitted and operational

Is the above a good recognized setup and what benefits would it give over stock. Is it worth keeping on the bike. I have never ridden a stock bike for comparison.
Thanks in advance

Seems like a re-flash and fitting a Power Commander is redundant. I think most tuning tweaks are possible via a well developed flash alone. Most would not consider a K&N filter an improvement. They don’t filter as well as an OEM type paper filter.

As already stated, if it’s been flashed there is no need for the Power cdr. I don’t know if Off the Road do reflash or not. The best combination would be a ecu flash in conjunction with a dyno and either Arrow or decated OEM headers

Welcome, from Texas. If you like the way she responds and rides, I'd just leave it alone. Only fix what you don't like. And I doubt there's gonna be very much that you don't like.
