hey guys
currently looking at buying a bigger throttle body for my car. just wanted to know if i do this will i have to get the flash tuner tuned again? and will it give me much more performance?

i currently have dual john bowe full stainless exhaust, growler intake, and the flash tune.

if anyone can help me with this much appreciated...

If you want reduced performance go right ahead.

The accessories turn slightly slower.. Takes less power from engine to turn them..

If you're going to do that you will gain something from a larger t-body. Plus of course the 290-up engines are more able to use the larger opening. The original question was on a 260 so it would only serve to make it more of dog down low.
