The largest thing I noticed was my ignition timing seems to like to fall flat after about 3 street pulls from 3500rpm upward. Even with the stock/base map and no modifications the first 2 pulls are usually substantially higher in timing than the subsequent pulls. Up to 8 degrees in timing in fact. Although there is a rise/change in oil temp, I didnt think it would account for such a difference in performance? Oil temps are not going above 220.

I think if I figure this timing issue out, tuning this car will get a whole lot easier.
there is a few possibility that im thinking other than what i said in our PM.
you might be running with to much ignition and&or leaner area which will screw your powerband .

if I'm running to rich (below 12.2afr on a real WB) from what I saw I'm losing a few degree in ignition
but not like it would if the knock sensor feel knock when too much ignition/lean spot.

its to find that sweet spot which will help you !
this is why I think the MAF table should be fine tuned even stock.
thats just to remove a small variable.
