Suggestion:
If you have a way to do it, get the car out to the strip and get some timeslips before & after. Might be a bit too late in the year though for that. Or with a Gtech or something like that. Its not going to be a world of difference, something you might feel or think you feel but could see it in the times and G's recorded.
Thats how I did the carb/intake shootout, "seat of the pants" doesnt work for me - it always feels faster if I spent time or Money on it, but that doesnt mean its really so!
