Hey guys i was wondering if any of you guys got your ecu chipped by JHPUSA.com. Let me know what you guys think. Are they good, do they suck. I looked it up on their website and they said they use a mugen program variant. It looks good, but then looks can be deceiving.


It's either this, or going for a Neptune.

Any ideas, advice, let me know what you guys thinks

Thanks and greatly appreciated
