PC Pro on 99

[Curiousgb]

Installed my PC Pro today and did a few runs to check it out. First impressions are positive. Interface is simple and easy to use. I really like the dial on the fly. I made my runs with my current SS maps in place, so I know that is going to need adjusting.
One thing I noticed is that no matter what rpm I am at if I go wot I get a short lean spike. I have included a shot of this from my wb. I don't know how it will show up.

Too small for my tired eyes. It may take a bit for the ECU to adjust or it might just need to be tuned to get the PC-Pro to match the SS. I would have to see the duration of the spike. If you punch the pedal to the floor, you might get a real quick lean spot for a few tenths of a second. Are you accelerating and then go WOT or are you cruising and then go WOT?

Post a larger picture or email it to me.

I started from cruising and went wot. The afr dips and as the boost goes up then there is a short lean spike. I will send you a full size via email.

Had a chance to make some good runs post pcpro install this weekend. I took a 200 mile trip (back roads). Had my PC hooked up and was tuning on the fly. Did I mention I like the tune on the fly option. I was able to get a good afr without fine tuning the SS. I will do that later.
I am still seeing a lean tip in situation and it, along with that, there is a noticeable hesitation when I am cruising and go to wot. If I ease into the throttle and open it up it seems fine.
Attached is an example of a run from cruise to wot. Any thoughts?

Can you post your PC-P's settings?

FWIW, I'm using Tom's map from his '99 for my fifth injector and it seems to be working well.

I did have to reduce the whole map by 25% since I'm not making as much boost (around 9psi).
