KenneBell Boost a Pump ?
Hey guys,
This 05 Saleen I bought already has a BAP installed. I noticed that the dial is set all the way to richest setting. Would this cause bad MPG? I'm only getting like 11 to 12 MPG doing city driving. I'm not boosting that much either. Can I mess with this dial settings for the BAP? How do I know how lean I can go with the setting? Thanks.

Honestly, the BAP is only engaged when it needs to be so if there will be any problem with you getting too much fuel it will be at WOT and you'll know it by looking at your A/F to see if your running rich.
Running rich isn't great for performance but it is also a whole better than running lean...lol
The point is - if the car is driving fine now, I wouldn't worry about it.

Seems to run fine except in the morning it likes to bog a little until it's warmed up. I just thought I should get like 16 MPG in the city doing normal driving and not much boost. I do get like 25 driving on long trips.

so modaddict..... is it safe to say that
the BAP setting = max potential fuel
pressure and that regardless of the
BAP setting, the PCM is simply
maintaining a certain fuel rail pressure to
achieve the desired a/f ratio?

The bogging when cold is most likely caused by the car running to rich, if you have a tuner you may want to data log the A/F to see where it is at when the rpm's are low and the car is cold. My car was having a similiar issue and it was the tune.

Well 11.8 ain't rich compared to my A/F ratio. I still get 18mpg driving back and forth to work, but that's 5 minutes of 45mph max speed, stopping at stop signs and then 10 minutes of 55-70, then another couple minutes of slow poke driving. On my way home I normally pass atleast one person and it's ***** to the wall!
11-12 sounds bad, but if you are constantly stopping and starting and sitting in traffic then that's probably about right. You can't get decent mileage if you aren't moving.
Since you are getting 25 on the highway i'd think you are fine. The bogging when cold doesn't sound right.
