I just bought a 1999 350 with a 7.3. Love the truck but has an exhaust leak at manifold. It's n shop now..how much would that effect performance. Common sense say a lot since the turbo uses exhaust to work. Am I right. Thanks and again I am loving the sight Tons of knowledge her for sure

WELCOME Aboard

Yer right. The exhaust drives the turbo compresser wheel that creates the boost pressure.. with any exhaust leak, pre turbo, yer loosing power/performance.

Got Gauges ???

If not.. when ya start tweak'n things, you can tear things up real quik.. whithout at least a Boost, EGT and Trans temp gauge.

Tell us about yer 7.3. Yearly 99 or 99.5 ??? Manual or Auto trans ???

Yes I do. It has the three pod pillar set. I checked out normal readings and I'm right there. I'm a gear he's at heart. This my first diesel though. Not sure if its a 99 or 99.5. I'm guessing I can tell by the vin. It has 199000 miles. It is chipped but not sure which one

Good to go on the gauges.

The VIN will tell ya.. but if you know someone with a 99.5, 2K or a 01, 02... you can tell by the Turbo "Y" pipe design.. as compared to yours ?

If they're the same as yours.. it's a 99.5+.

Which one is better. Doesn't one have a better turbo. Wicked wheel or something

Very Simply Put ?.......

It's not so much which one is Better ? There were some subtle "Improvements" in mid year 99.. turbo and charge tube wise.. the 99 had what is now refered to as the "Wicked Wheel".. Stock. It whined/whistled.. average consumers did'n't like that.

Ford/IH changed out that turbo set-up on the 99.5, and up. It was quieter but has a Surge issue @ 15 to 1800.. rpms. Lots of us put the 99 turbo wheel on our 99.5's, and up. There is also some ECM/PCM programming differences.
