so i'm going to be putting a turbo on my 03 gs in the spring, and i was thinking of getting the jet chip for the piggyback one in summit/jcwhitney. would the chip help the turbo more or would it make it run like ****?

 

no chip please. Go to tearstone, you can use the stock ECU and have it flashed for fuel and timing trims suitable to run safely under boost or you could go the tearstone route using the Greddy Emanage
