drove the car home and it was fine. made full bost and was nice and fat in the A/F. let sit for a few h and took it out again. around 3-4psi A/F starts to climb and leans out,

im running LPA twin intake set up with a hobbs switch. both pumps are working properly hobbs switch is working and car runs fine out of boost.

is it possable for the FPR to be shot but not doing any thing abnormal?
dosent crank very long during start up, under normal driving A/F is what it has always been,
latley tho it has been droping off the gauge when shifting 16+:1 and motor feels like it wants to stall out when returning to idle after being reved slightly with no load on it


help please

First, remove the BAP as I specifically state not to use them with my dual pump kits.....
You are risking pump damage when they will easily support over 300rwhp more than you are currently making.

Second, call me tomorrow to discuss.

When any of my customers have an issue, please call me first. Your questions will be quickly & correctly answered.

Please have fuel pressure info ready so your problem can be quickly diagnosed.

i said there is no issues with you kit. it is working amazingly. the switch came with your kit. i mean a Hobbs switch, sorry.


im asking about the FPR witch was not aprt of your kit. if one that is faulty can work fine under vac and start to fail under possative pressure

As far as a BAP, I'm glad you typo'd that & are not using one.

I have seen some regulators not boost reference correctly & act erratically.

Being that you are a customer of mine, I will always help you out even if it does not relate to my parts.

Feel free to call.
