A Phoenix PCM is worth about a second a lap at most tracks, which is a huge margin. I have three PCMs, Phoenix tuned hot, cold and stock and I've swapped them out often enough to confirm that they are worth my money for what I'm using them for. :cheers:WhosUrDaddy said:Sub -
Does engine tuning help with road racing? Or does it just eek out a few ft/lbs and smooth out the torque curve for smoother, but not higher, performance?
Anyone have thoughts here?
