doing some research on a tune for my stang and heard somewhere tuning an engine other than factory tune will cause premature aging of an engine just bought a 30k car need the engine to last to at least 150k miles is this true or just a bunch of bull?

 

 

B.S.

If you modify your engine, and don't tune it, then you will have problems.

 

and that's how you want to start.

 

 

I'm in. As long as it's a good tune, no worries.

 

+1 Dyno-tune it...get the A/F right, timing right, ensure no detonation...

 

Might even help the engine last longer as the tune could concievably run the engine more efficiently than stock.
