i just got a mail-in flash .. i'm not 100% what version i got... lol... my tuner Aniel helped me ship off my ECU ... i didnt have time with school anyeverything.. (it was done this week)

the Car feels GREAT... pulls hard.. but i'm not sure if it's bc of the sudden cold weather in the 50's of the tune... the reason i even question this is bc the boost doesnt hold any more... before the mailin (and fuel pump) ... i use to hold boost.. through the WHOLE gear.... if i ever dropped it was like .5 psi...

but now after the mail-in i cant hold boost... tried upping boost and lowering boost to see if that would help... nothing.. i still lose boost.. (i'm hitting 19 dropin to 17)

Al can u help me?

 

Talk to your tuner - sounds like you have a boost leak which developed

its very comon that when cars get tuned they start pulling harder and loosen up bad vac or boost connections

 

word.. ill take a look at that tomorrow... u think the stock BOV could be leeking?

 

What are your mods ?

 

injen intake w upper pippin,
hallman MBC,
invidia dp,
invidia catback,
de-cat
fuel pump,
exedy twin disc

 

With the Hallman MBC your bost should be holding within 2 psi max drop

A boost leak is prob the most likely cause
