these things are amazing def a turbo car neccisity i used it so many times on my dsm, found that i had a leak at the manifold =]

 

check for a crack on the manifold!!!!!!look around the manifold for black dust on the block and stuff.....

 

ahh yess perfect...i forgot all about pre-turbo leaks....they kill! look for any leaks at the turbo manifold and where it connects to the block and turbo, but also check all pipes

 

i would think that if it was exhoust related his afr's would be more to the lean side...

 

wanna see my perfect explanation to a decent afr with a pre turbo leak and boost leaks..

the boost leak in pipes will cause him to loose bost and run rich, which is whats happening if the car stutters upon wot, this will cause a rich afr then add an exhaust leak(which adds leaner readings....you have a decent afr =]



LOL


check pipes...clean maf, check vaccum lines and manifold

 

Check vac lines. If it is cracked or split, it will do the same thing

 

my air fuel was fine when my manifold was smiling ( the crack looked like a large smile) my car would hit full boost late but didnt even spin 1st...i knew there was a problem....im puttin my money on a cracked manifold

 

bring it to the shop. we will run a boost leak check.

 

wow kinda freaky

 

so went down to a local shop and they tested for a boost leak everything was fine. THey checked out the fuel trims they were fine as well. So it looks like the culprit was the temperature in the last week the temp has gone up from the 50's and 60's to the 80's and 90's. I guess i didnt realize how much temperature could effect performance. Also im probably use to the power so it may not feel like it used too. The temp is also why im assuming my afr's have gone so rich under boost. Hotter air is less dense thus less air to fuel. It was tuned in like 40 degree weather.

 

I had the same problem, My car runs like a beast when its either cool or cold outside. But when its 85 to 90 degree weather here in florida it runs like poop somtimes dam hot weather go away. I wish it could stay at 70 all the time

 

lol i felt like a douche at the shop. They tell me nothings wrong and im like but but but theres no power. then i think about it and it literally went from a 50 degrees to 90 degrees in like two days

 

 

i know crush but at least my car is fine

 

its really amazing how much temperature can effect performance

 

very true, wentr from 62 one day to like 95 the next, colder air u feel more power, warm air eh not so much

 

were you tuned in ptuning's dyno?

 

yessir

 

Is their dyno climate controlled? if so you were prolly tuned with 0% humidity.
