c5z tuning question
I currently am Dyno tuned with intake headers/xpipe into the stock TI's. Tomorrow I'm throwing on a pair of Corsa extremes. Do i need to retune? Will the new catback cause it to run more lean or rich? If any. Thanks!

With the new catback you should not need a re-tune. Catbacks on these cars are pretty much just for sound. So likely wont change your tune enough (if any) to need a tune.

I agree no retune is needed However your fuel trims may change somewhat---Driving your car normally for about 50-75 miles will allow all your fuel trims to "learn out" and eventually settle on "0" causing NO addional enrichment at WOT ( a negative fuel trim will never SUBTRACT fuel at WOT as a lean safety and will lock on "0"
