I have no allegiance to anyone or any company but going by what I've read, mainly here but also other forums, my money would either go to r-tech or badger5. And will be.
Map wise, I doubt there's much between the two but badger has actually helped me on the phone and I've bought a few things off him as well so will be going to him for the map.
As far as revo is concerned, at least just my opinion and from what I've read as least, their maps seem to give a lot of boost and a lot of torque which naturally makes the car suffer at the top end compared to others. Having come from a vtec, I need a top end!
Jabbasport I know nothing about, didn't even know if they were still in business tbh.
If distance is an issue, make it so it isn't! If there's one thing worth travelling for IMHO. It's the map on the car.
