If you got one I've got some real nice 50 pounders in my car that would work nice together......in my car that is haha. Seems like most people go with 60 s in almost every arrangement because it leaves you room to continue to mod without running out of injector. As long as Eric at TT knows what you got he can tune it to work. There seems to be an abundance of good used 60s on the for sale area as well which is nice if youre a budget minded gear head.
