yea, do a before and after dyno and let the numbers do the talking

 

I currently run a devilsown kit on my turbo honda accord. Its probably one of the best mods ive ever done....i dont know why more boosted honda guys dont use it. The domestic crowd has been using it for years now. It greatly reduced charge temps and of course cylinder temps. I use a 50/50 water meth mix. I mainly got it for those highway runs where you're boositng in high gear or on the track where i run really high boost. No more blown head gaskets!

I think it would be pointless on a TL unless you're running some sort of forced induction.
