Re: 91 vette going slower (6spd)
I think I had the same problem when I changed to 24# injectors. Mine would hesitate badly from low RPM. Lowering the fuel pressure and having the chip reprogrammed didn't help. Eventually I had the original GM injectors cleaned at Cruzin Performance and put them back in. Hesitation disappeared and the car just seemed to run stronger IMO. Probably not what you want to hear - just my 2 cents, when I posted this problem 6 months ago a lot of guys using them said they had no problems.
45 PSI sounds like too much FP for the 24# injectors, you might be too rich as well.
