is it necessary to buy a whole new performance chip when you buy the s/c with the pulleys, headers and exhaust?

you don't buy a performance chip, you buy a piggyback ecu, that alters the fuel and ignition timing of the stock ecu with the trd reflash.

and no, it really isn't necessary until you change the intake because then you start to run the risk of running lean and blowing your engine.

performance chip? you can't chip tc's -> the sc come with a flash for the ECU and if you add mods the best bet would to get a piggy back and tune it. Others have had no issues with those mods and just the flash. Don't take my word for it though, im going the turbo route. Anyone with a SC want to post and add comments or correct mine ?

so all i have to do is get it tuned, btw its gonna have performance headers and a full exhasut system

if you use the TRD tune, you won't need to get it tuned...

When you buy the supercharger. It comes with a module that holds the tune for the supercharger, The dealership has a tool that hooks up to the ECU and it rewrites the map in the ECU. The car is now tuned for the supercharger.
