I was considering trying the turbo city injectors with the spacers and tbi spacers.. I have made several mods already. I am running a performance chip with the tes headers. I would like some opinions.

Don't waste you money on the turbo city injectors or spacers. Do the ultimate TBI mods yourself from the technical articles on this site and you will gain more hp than the turbo city method for a lot less $$.

Spend that money on other speed goodies, like gears, posi, or LT1 cam to complement your setup.
