Never Hit Fuel Cut anymore? Kinda Scared

[BlackMount]

kinda bugging me...


ever since I got my car running 100% right I dont hit fuel cut anymore.

even when I over boosted up to 26 psi I didn't get fuel cut. and it was more then once too. by accident tho

only fuel mod I have is 255 Fuel Pump. but I thought it was useless with out higher output injectors too. am I wrong?

whats going on here?

Enjoy it..

Although most important thing to remember is to make sure you air/fuels are where they need to be... you might not be hitting fuel cut but you'll definetly be running lean

Even if you have bigger injectors you still need to use something like SAFC or get your ECU flashed to prevent fuel cut. Like this...

Some of my friends have experienced this same thing though, it's weird.

is your maf hacked? id hit fuel cut at 18 on a 14b in my 1g (could of had boost leak to) do you have a logger? also a wideband would be helpful to keep an eye on your afrs

14b 26psi, stock engine, something has to be at its limits. i would start trying to see why it did that and fix it so it doesnt happen again.

Times I've all hit Dangerous Boost numbers (22 PSI or Higher) have only been for short periods or I did not know I was at that high of boost.

the 1 time I didn't know I was running that high of boost was when my MBC messed up and my Boost gauge quit working at the same time. Thought I was still @ 15 PSI...turned out I was pushing close to 30 Psi.... Resulted in me blowing the turbo @ 135mph...no fuel cut....that's what worries me.

other times have been tuning my Homemade MBC. (Currently on stock boost due to fresh Cylinder Head + Gasket)
