I actually did some searching up on it and found reviews that they were garbage. They say to take it to a tuner and let them figure it out.

It's not even a matter of a small incremental increase, it's how are they achieving those numbers. Need to see AFRs and all of that to know if it's something reliable that won't hurt your engine over time

I know of Force Fed Motorsports in Sacramento, to be honest I don't know enough to vouch for them and I think they're website is temporarily down at the moment. Worth a try to maybe check out reviews and what not ?
