I'm using a 2800 stall and mine has pretty much no lag. If you're curious to see for yourself, I have some videos; jylp4u on youtube. Also, I should mention that I've pulled the motor out and apart. I found that I had 2 blown head gaskets... So, on a soft tune 10.6 A/F ratio and 18* of timing; leaving at 3psi with the boost set to 24psi and creeping to about 27psi, I was able to get a 1.8 60ft and ran 11.225@125 mph. That's with blown head gaskets mind you... #6, #3 and #1 cylinders, one layer of the cometic gaskets split, but it wasn't noticeable until it went over 24psi... I could've left it alone and just played with the tune a bit more and got it to run off into the 10's, but I figured I should just pull it and go over everything to be safe. $750 for that kind of performance is very hard to beat.
