Alright guys, im to the roof with this issue im having. I run a 150 wet shot through a nitro dave 92 plate. however that 150 shot has never felt...well like a 150 shot. I run the 62/32 jets. my wideband reads way rich (10.0). It will read 10.6 for a split second but then right away go to 10.0

Whats the smallest fuel jet some of you have had to go to on a 150 shot?

Ive tried lowering the fuel jet, lowering the dedicated's pressure, and it still reads 10 ******* oh and doesn't feel like a 150 shot. I even swapped nitrous solenoids thinking i had a flow restriction. that didn't help.

 

What fuel pressure are you running on the dedicated system?

Also what kind of fuel are you using in the dedicated system?

the dedicated is at 55 psi. and ive tried running c16 in it and even went as low as crappy CA 91. still reads 10.0 and doesnt hit the way it should hit.

 

Ok well it looks like the pressure is about right. What have you lowered the fuel pressure down to and what was the smallest fuel jet you used?

Also what kind of wide band are you using?

Have you looked at your MAF readings to see if it's wigging out? Occasionally we have seen MAF voltage do funky things if it's close to a plate.

First check everything that NX has suggested above.

 

Are you reading plugs to confirm what you are seeing on the wideband?

 

Id bet the rich reading could be wrong. could be lean or a timming issue making it not "feel" correct.
