I have a stock 172 and i have bought a 182 4-2-1 manifold and I have RSTUNER too.Do you think that y need a new custom map or 172 RSTUNER stock remap will be good?

If you're going to all the work of fitting the mani (although from what I've read it's not the best mod in the world) you may as well get Fastchip to do do a custom map for it. It doesn't cost that much does it?
