Fwiw, JMS is a good shop. They tune very well. I really don't think you can go wrong with either kit. I don't know their track record with this kit,but I'm sure the tune is fine.
We do have over 800 cars running the mongoose kit now. The tune is spot on,we pride ourselves on making sure every car with it last as long as possible.
