If your going to make the move to the translator and LS1 or LT1, go with the Tranlator Plus and the Extender Chip.
This will allow you to tune the timing at both end, idle and WOT. The Translator only allows tuning of the fuel at idle and WOT.
Besure to get the Extender chip for your injectors.
Extender cables are also available to mount the Translator inside the car. Check out my website for pictures.
