Well folks,
I just got back from the dyno; boy what an experience indeed. My thoughts and street tune were more off than I ever would have thought. I admit that I must have been fooling with the wrong maps/ideas because my 1st and 2nd run were noticably lower than the stock dyno pull. For the third run, I switched back to the stock base map and the loss became gain; the car returned to stock power for the most part. In all, the tune I've been working with dropped my power by more than 10-20 hp/tq. Not good.
In my disappointment, I must realize the mistake and take this as a learning experiance. Take one for the team so-to-speak. After mulling for a few hours, I've reset my maps back to stock and am anxious to start again from the beginings.
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.
