stand still launch and highway differences

[spectr019]

I installed PTE 680cc a few months ago and retuned it doing 3rd gear pulls using the wideband. Had most of the afrs at 11:1, so I thought I was doing alright. Went the track the next day using these settings, I was running 13:1!!! So I richen everything WAAAY up so I'm around 10.5:1. I didn't have many runs to do, they caught me doing 13s and I didn't have a helmet on me so I couldn't run anymore...Next day, back to tuning doing 3rd gear pulls, and I'm back to 9.5 or around there, so I lean it out again. I've checked for leaks everything, have even recently replaced notorious gaskets (intake manifold, throttle body pieces, etc...) and I can't find any leaks to make me run so rich. I'm tuning with an SAFC II, have a re-wired 190 pump, and as said, I am using new (not new to me, brand new units) PTE 680 injectors. Any ideas besides me thinking to search more and more for leaks? Thanks for your advice.

I had an issue like this, Ceddy pointed out that my MAF had a bad baro sensor.
