‘05 S-197 GT (4.6L v8) - my first Mustang & love every part of it! I want to start tinkering with the engine, but I get different answers from folks on whether the changes I’m after will require a tune or not...
The car is bone stock - ran on the dyno & had the air/fuel get as low as 10.8:1, which got me thinking about putting on a new intake (cold air w/ K&N) & headers, and some folks say I’ll need a tune, some say I won’t.
What are your thoughts? A few changes like these wouldn’t require a tune, would they? And when you do get into the hardware that requires a tune, what can the 4.6L handle? Any feedback would be great!
PS: I’m probably gonna swap spark plugs too with the air/fuel situation, but all the mods have to wait for Xmas money!
