I have that... It's called HP tuners. I also have a gauge that switches between alot of those as well. I don't use EGT gauges for tuning I was just asking a question about cylinder temps since the EGTs are a reflection of how efficient an engine, to include a turbo, is doing 'work'. I guess I was just a little confused with your response is all... You second one cleared it up though, thanks

Yea depending on the tuner for my current car, you will see as much as .86 lambda at WOT according to the wideband in the exhaust manifold.
