Thanks gmtech, that does help - that is essentially the reveiw and info I was looking for. I've seen some of your discussions on cam tables as they relate to response and cruising economy, but I'm not ready to take the hit on mpg yet if there are other ways to sharpen up the response. FWIW, my DAL table is not much different than stock right now - the minor changes from stock are only in the 90-100% load columns. So, I'm sure there is plenty of room to adjust the lower load columns to tweak throttle response.
The situation I'm trying to adjust is the one where the car is cruising along in the range of say 2500-3000 rpm at low throttle (<<50%). Then you punch it. There is a very noticable lapse between the pedal hitting the floor and the car taking off. Everybody with an LNF has seen it, everybody's felt it. It irritates me that a car primed to be one of the most responsive turbocharged cars ever, with direct injection, variable cam timing, and a perfectly suited turbo for low end response, ends up being limited by a 1-second lag in the throttle plate opening when going from low ETC% to WOT.
For comparison, my other car used to be an M62 supercharged 2.2L eco sunfire. If you put that car in the same situation (light throttle at 2500 rpm, then punch it), the instant push put a smile on my face everytime, even though ultimately the car was not that fast (213whp at it's best). I'm not expecting that kind of "response" out of the solstice, but there has to be some improvement to be made over how it is now. I'm taking tomorrow to do some work on it, and the LE5 TB is on the list. Based on your review, I think it is a step in the right direction.
