I'm not going to mention where or when but it is what I am running off the spray best case on 93. You guys can figure what the spray would add anyway. A 2.9, k&n, bassani xor and catback. 12#. As you can see the a/f is ok for a boosted mtr, it reads right along with my lm1. Since we got into this domestic/import stuff, thought I would post this up. I don't really care what # say. But you can see what a p/d s/c does as rpms goes up the airflow increases till it runs into restriction. Btw it takes approx. est 80hp at 6k to turn the s/c per eaton. So lower, higher etc. what do you think? No questions on the dyno or when don't want to go there. Same old tune anyhow.

very flat torque curve there Rob, no wonder its tough to hook up, thats alot of torque at 3000rpm!!

yeah, its funny to see how fast the torque and HP curves go up as the supercharger builds boost. you dont see that very often with turbos; at least not that low in RPM range...

Now I program timing down 5 deg total. Same day, within 50 min. of the other. I did confirm what I could tell driving the car or using the gtech. Actually my timing curve is pretty flat at wot loaded from 3k to 6.5k. Anyway you can see a difference across the range in hp and tq. I started with this actually, did spray, then added the timing. So the engine was hot all along no cool down just like the street.
