ckinyon Posted February 16, 2016 Share Posted February 16, 2016 10k on new engine. Auto transmission. 2005. So i have been having a problem of random loss of power while accelerating. Usually in 2nd but does it in all gears. I have a 16g bnr turbo, turbo back exhaust, and a slightly better than stock fuel pump. Any ideas on what might be wrong? Any help would be great If this is in the wrong place im sorry. New to this stuff. Sent from my SM-N910P using Tapatalk Link to comment Share on other sites More sharing options...
apexi Posted February 16, 2016 Share Posted February 16, 2016 I don't know much about upgraded turbos and the LGT, but based off another thread I read recently I have to ask, do you have a tune? Link to comment Share on other sites More sharing options...

Kcco138 Posted February 18, 2016 Share Posted February 18, 2016 .....But did you get a custom tune or just use the OTS cobb tune? You should get a custom tune since you switched out the stock turbo Link to comment Share on other sites More sharing options...
Mike07LGT Posted February 18, 2016 Share Posted February 18, 2016 Yea you might need a new shortblock... I would have a compression and leak down test done if you don't have that turbo custom tuned 03 WRB WRX (RIP) 04 JBP STI (sold) 07 DGM Legacy GT (RIP) 12 OBP STI (DD) Link to comment Share on other sites More sharing options...
Hirschman Posted February 18, 2016 Share Posted February 18, 2016 .....But did you get a custom tune or just use the OTS cobb tune? You should get a custom tune since you switched out the stock turbo This X 1,000. You NEED a custom tune with the 16G, it flows a lot more air than the VF40.
