Questions for Frederic

Hey, I was referred to you from our fellow V10'ers. I have some questions for you if you might help. I'm in the beginning stages of fabbing up my turbo setup and this will help me much in the future. I'll be putting 8lbs of boost to it. OK, on with the questions.

1. If I swap injectors on my '99 V10 F-350 from the stock 19lb/hr to 36lb/hr ones, do I need a MAF that is calibrated to the injectors or is it handled by the ECM.

2. I'm getting mixed answers about an adjustable fuel pressure regulator. I have a BBK unit from a '97 4.6L. BBK and a few others tell me this will work on my V10, some others say it wont work, do you know if it will?

Thanks in advance.

Correction: I found out about the AFPR. BBK lied to me and said it would work. The pump adjusts the pressure according to demand.

I also found out about the injectors, I was just wondering how this is corrected. Increase or decrease in pulse width?

If you don't want to do a tune for your truck theres ways to do it. Qeustion is how do youwant to do it?

1-I'd reccomend you hook up your wide band O2 meter and your diablo set up to view load, once that is done and you know which loads are rich and lean,

you know to let more air by the maf then there really is if your lean and the oppissite for rich, some do it via a bleed off valve connected in parallel with the maf or you could use two potentiometers electricaly.
