cronic, i use my egt gauge to roughly tune fuel.
if im running too too lean, my egt's will climb like a mofo

If the timing is not sufficient, it will become obvious when EGTs go up as fuel is added. I have seen this first hand with my Dodge. Its pretty spooky when you add 75-100 hp worth of alcohol and the EGTs go up 150 degrees with the exact same advance and no knock retard! But, it confirms where the problem is conclusively. All that extra fuel is burning too "late".

Also, that's very good power for a t3. Matter of fact, it's crazy power with a t3.

Turbo was a T3 55 trim (teeny tiny bit larger than the more ubiquitous T3 50 trim) in a 0.42 A/R comp housing paired to a standard T3 turbine in a 0.48 housing.

No I don't shit my pants, because 14b's are still efficient at 20psi (actually that's about where they stop being efficient, and you dont run more then 20 on a 14b)

An egt is not a safe way to tune, I realize a narrowband will _roughly_ show you that you are rich or lean, but it's NOT a great way to tune. Neither is using egt's to tune timing. From my understanding it's much more accurate on a dyno. Since he was ON a dyno with a wideband... I was curious why he did things the hardway.
