Hey Mike, couple of questions:

1. What is your boost-a-pump controller set at?
2. Have you checked the output voltage from the boost-a-pump?

For question 2, if you have a Fluke meter with MIN/MAX on it, you can use the MAX feature to detect the highest output from the BAP. MAX is also handy to test the MAF. :D

Shouldn't the BAP output be a bit higher than 17.7V? 13.8V x 1.5 = 20.6V. Maybe KB would know. Call em:

KB BOOST-A-PUMP FUEL PRESSURE

If you are not using the KB chip, the BOOST-A-PUMP will not work.

I don't know how that could be true because its not like Kenne Bell is using any type of "special" programming in their chips. It seems like these problems are because of user error and not product error. I'd call Kenne Bell and ask them about the problem before saying this stuff.

KB BOOST-A-PUMP FUEL PRESSURE

I talked to KB and they said that they are using a special program to make the BOOST-A-PUMP work. If you are not using there chip the computer will sense the increse in pressure and reduse it back to the stock pressure.
