Tuned my VE and got it spot on... Tuned my MAF and got it spot on... Turned the the STFTs and LTFTs back on and it runs rich everytime i'm in boost. From the reasearch i've done it's because my STFT and LTFTs are adding fuel and therefore adding fuel when i'm in boost. So, i turned the LTFTs off (STFTs still on) and now it's running exactly where i want it to...

You guys see any issues with keeping the LTFTs off?

 

I don't see any issues. I run mine with them off.

 

Mine are off but I'm not boosted. Hopefully someone can help you out.

How rich are you getting? if you're in boost you should get into the 11's

 

with them off at 8 psi i'm dead on at 11.5 which is where i want to be.

with them on i drop to 10.4-10.6

 

-No.-

 

I do not run LTFT's either.

Really you should find out why your LTFT's go "+" which adds to your Pe. I assume your Ve and MAF were dialed in here. For me it was a combination of a big cam and the fact my primary O2s only measure the last 2 cylinders on each bank.
