True true. Check thread, I have an LS Trans. Does this change your recommendation? By what you say, I would have a problem ustilizing a GSR cluster. A more technical explanation like the one you gave me makes more sense to me than layman's terms. Don't hold back, slugger.

With everything I have read above, I need a more dense tach, not LS and not GSR. Seems like it needs new math to encompass the LS trans on a higher revving motor. Can I get hallelujah? So basically, I need to install a TV that plays porn 24/7 where my tach is and go for an Autometer Tach.

With that said, anyone know where I can get a tach that won't show off for the thieves?
