Finally received my chip in the mail yesterday! Now, I am just waiting on my proforce exhaust to come in. I order them last Sunday, so hopefully they are here before the weekend or early next week. I wonder why my wife is pissed with me at the moment? Hmmm.
with chip i'm running
15 air fuel ratio
dyno 300.2 whp 312.5tq
with out chip
319.5 and 311.5tq
air fuel 11.6
I am not very familiar with dyno's, but what i see in the graph is that it starts at about 4700 rpm. What happens in the lower rpm range that you use 80% of the time?

The truck will downshift at a lower RPM. You won't be full throttle below that point.

Keep us posted on the results !!!!!! She'll get over it .

that a/f ratio goes along with what I have seen on my wideband. the chip is too lean...not that they probably can't fix it, but gosh we don't need any blown engines.

red is with chip

I am interested in seeing the a/f ratio on my truck w/unichip. What would you guys recommend...would a scan gauge work II? Obviously, I could take it to the Dyno, which may be an option down the road.

I'm gonna say that it won't. I believe the unichip alters the 02 voltage before it enters the ECM, so the 02 readings with your scan gauge would be off.

That1Seven, were you running premium fuel on map A and B, or regular fuel? If the lights started blinking, I'm sure your truck went into safe mode while on the dyno. These trucks really don't like being on dynos. I had the same issue with my RX8, it was almost impossible to get an accurate hp reading because it would always go into limp mode if the rear wheels would spin faster than the front for a certain amount of time regardless of trac/stability control being turned off. However, 15:1 AFR's is very dangerous. Call them and see what's up.
