What do you have done to your engine and what kinda horsepower are you pushing? I've got a vvt motor to put in my NA, and I'm thinking about getting a 6258 as well.
Specs: www.reddit.com/r/Miata/comments/njv29u/370hp330lbft_and_it_looks_stock/gz9jdq7?context=3 In this run I have 320hp but I have a 270 and a 370hp tune on a switch.
