Kb Bap q

I got my car tuned after I did the BAP install along with dual fpdms, 340 striker pumps, wiring upgrades. Then shortly after, I removed the BAP and sold it, thinking it wasn't needed for a ported eaton. I've been running without the BAP ever since. Question, do I need a retune now since I removed the BAP?

Thanks!

Runs good and A/F stays in the mid-11's through the 4th gear pull, but I don't want to blow my motor by having removed that BAP. Should I buy another and re-install or is it fine as is?

What is your FPDC? if its at an acceptable level 90% or below leave the BAP off. The BAP is just a fuel pump booster so it increases the output of the fuel pump. The computer regulates the fuel pump voltage to maintain a constant fuel pressure.

By removing the BAP the ecm will have to command the pumps work harder to maintain pressure as long as its under that range I listed above you're ok.

Awesome, thank you cj. FPDC is mid 70's

EDIT, just seen your previous message. Should be fine in the 70s
