http://abmods.com/ Adam is a stand up guy. He has a really nice dyno to show you what he has done and can recommend a proper pipe at the same time.

Welcome aboard ducktape. First off, if your going to
ask for advice about a modder, it would be nice to
know where your located. You can, add your location
under your nickname. As far as modders for GO engines,
22racer(Rex) or Mr Twister (Brian) for a descent mild race
mod. If you want to step it up a notch then get in touch
with Maximo (Neal), he knows his stuff about changing
the port timing on these engines and can make your engine
as radical as you want. AB Mods (Adam) is also a great modder.
All of these guys are good people to deal with and I have and
will continue to do so. Murman mods is another modder that I
hear good things about and I plan to have him mod one for me
in the near future.
There are a few that I would stay away from, I'm not
going to mention there names, but if your thinking about
anyone that I have not listed above. PM me before sending
your engine out. I may have some important info for you.

I have had mark at powerhousercperfoemance.com mod 3 engines for me. Every engine was very very good the performance gain over stock was very noticable and if you talk to mark on the phone and tell him what you are looking for ie more bottom, more top, more runtime etc he well do just that. Mark did the impossible to th grp engines he gave them bottom end and kept their fuel mileage in the 11-12 min range.

Clockwork Does all my gear....Im actually about to test a 21/7 this weekend...broke it in last night and installing it in the next little while....also testing the new M2C weighted flywheel which should be pretty trick in buggy.

Honestly, I would run it stock. You're not losing races due to lack of horsepower, you probably just need to practice a little more. None of the top level team drivers are running modified engines - they're all stock except for the occasional prototype test parts they run.
Everyone who modifies engines will tell you that you get more of everything, but my experience tells me otherwise in most cases. Set-up the engine properly and tune it well and you'll be able to compete with anyone as long as your driving skills are sharp enough. And don't expect more horsepower to help make up for the mistakes - in fact it's usually a contributing factor that leads to more mistakes.
I've been doing this for Nearly 30 years, and I haven't seen a modified engine win a big off-road event since the advent of CNC where those special features that used to be too expensive in the hand-mill era are now standard and easy for the engine manufacturer to implement with a CNC machine.
Modifying an engine is tricky business, and the ones that do it correctly will do so in a manner that you can't even see the work that's been done. Not because they're trying to hide it, but it involves modifications that are not visible to an untrained eye. All the polishing and extra "fangs" in the sleeves are mostly window dressing except for engines that can REALLY use some flow work, but even then the gains are hardly measurable. Polishing is even detrimental to the performance of the engine because it causes fuel to "stick" and flow less smoothly. In the case of the sleeve it loosens the fit between it and the block, which causes a loss of performance. The modifications that produce really good "numbers" are much more precise and require some pretty sophisticated equipment to measure and map out effective changes.
The long and the short if it is, there are far more people that do it wrong - you can count the ones that really do it right all around the world on one hand. More importantly, you already have enough power to win races. There's no amount of horsepower that will beat good driving skills.
