ok so whenever i start my car after not being in it for a couple hours or more and let it warm up completely it falls on its face every gear when i hit boost. when i first accelerate in every gear it feels almost as if the wastegate dosnt open or its not getting fuel? but the second time or any time after i accelerate and hit boost in any gear the car works fine??

 

heat soak or boost leak.. prob

 

i thought of a boost leak but if it was a boost leak it wouldnt work fine after i went through the gear once it would still leak. and heat soak. this is when i first start the car and start driving

 

Fpr?

 

Might be knocking and pulling timing.Mod list?

 

Injen upper and lower intercooler pipes
ams front mount
full 3 inch exhaust
255 fuel pump
MR diverter valve

this problem just started happening outa nowere. well i actually noticed it happening the day after i first started my car without letting it warmup and took off in every gear about 2 weeks ago

 

Sounds like you treat your car well, I wonder why its doing this???

 

prob a boost leek. try a leakdown test

 

I wouldn't call this out of nowhere and it's very likely that you already answered your own question. Stupidity like that can cost.

 

+1

Boost on a cold motor is a bad no no.

Anyway check all your vacuum lines especially your fuel pressure regulator line.

Then do a boost leak test.

 

Do you have a AFR Guage and what are you reading when it falls on it's face?

 

yeah mine did this b/c of the fpr vacuum line...found it doing a boost leak check..plus i found another small leak

 

do you a stock airbox? sounds exactly like leaving the clips out of the snorkel on the factory airbox.

 

nah its an injen filter at the end stock airbox is gone. and no i dont have an AFR gauge but i will be doing a boost leak test soon i guess and buying an AFR guage soon because im sure that would show alot of whats going on.

 

The reason i didnt get an AFR guage yet was because someone told me it dosnt work with the stock ecu?? dosnt the AEM AFR kit have a computer or some brain of its own that dosnt even connect to the stock ecu or what?
