Ok, my car boosts 10 to 11 pounds like it always has...always pulled super hard. Well here lately I am still producing the same boost levels, but the car just spools and doesn't really pull. I'm throwing a code for a rich condition and o2 sensor out of limits, I sprayed maf with maf cleaner two months ago and the car pulled like crazy all over again but it seems to be happening again...this time I found a vacuum leak and capped it off, and the, I guess "boost lag" is happening again, but it can't be lag cause I never feel the power it just boosts but doesn't pull...I can't think of everything else, bit I am changing the oil, and I suspect an exhaust leak and I am changing the oil tomorrow and plugging the secondary o2 housing that I think is now missing a plug...just not sure if that could be the cause of such a big issue...also afr tends to fluctuate quite a bit, but it was tuned by shawn at ramey and the tune was a solid tune never any issues till the past 6 months so I'm just trying to corner the issue and get it fixed. Any info anyone needs from me to help, just ask, I can answer any questions about what has been done to the car, what I'm running ect...

 

leak

 

how about you start with what kind of car.

 

It's an 07 tc running 60 trim td04, tial 44mm gate, 550cc inj, return fuel system, walbro 255, on aem fic

 

Wow...you have provided us exactly fuck all good information.

 

All vacuum lines and couplers will be double checked again tomorrow, this only seems to happen when I hit 8 pounds and up, hoping maybe as simple as a cracked coupler and when I hit boost it flexes open....but that's in a perfect world.

 

what was the ambient temp when you had your tune? a 40 degree drop could alter many things.

 

WELL, lets all gather around and sing kumbyah, and shit will work perfectly, won't it?

 

I'm pretty sure it was 60's when he tuned it, but it happens when temp is in 40 or 50's as well.

 

you are a fruit.
