Questionable power?
I've been looking for simple bolt-ons that help my 92 breath easier. So far, I've added a TPI Throttle body plate and a Breathless Performance Throttle body bypass. Both did add nicer throttle response and were good for a few cheap horsepower. I was overall happy with them. While browsing catalogs, I've seen adds for (Kirban?) Throttle Performance Switches. At 70% throttle, they boost the throttle open signal for better timing. This seems like a nice enough idea, but can anyone tell me if they have tried it, or their opinions? Thanks guys, keep the Corvette wave alive.

I thought about it, but decided against it. It seems that all it did was at 70% throttle signal WOT. That just took away my ability to operate at 71-99% and would likely take longer to effect given that I would have to think about how much throttle I wanted... ie do i want 66% or 100% and how far do I push to ensure I get one of those two scenarios.
I decided to put a adjustable TPI in instead and adjust the setting to give better performance as per a number of threads that say stock setting is .4 volts at idle and setting in the .56-.60 range gives more fuel (power) earlier during acceleration

I haven't tried them, but I've read enough posts on here that have said they are a waste of money that I'm staying away from them. If you want WOT then just push the peddle a bit harder.
