Ok .. used a OBD ii 2 reader on car because it seems to run in a “ granny “ mode since ECU replacement.... i hear turbo spool but no PSSH sound .

NO DASH FAULT LIGHT
NO WRENCH LIGHT

Idles under 1000 rpm - stable
Rev up and release - idle normalizes
Driving car - seems fairly normal but no real pull in 3rd. Seems like im in some kind of valet mode. I heard ECU needs to re-learn driving habits to setup - . But will double check intercooler hoses and such ( maybe boost leak ? ) or ?

Not sure where to start . There is NO TUNE installed. Should I disconnect neg. and let ecu clear ? Or where else to look.

Help

26000 miles on Fist 2014 ( a baby still )
Whoosh intercooler
Ingen cold air intake
Boomba symposer delete
MRBP exhaust

ECU was replaced by ford ( free ) driven about 150 miles SINCE ECU was changed. Feels underpowered at 2 and 3rd gear .... No engine lights or irregular driving just noticeable lag ( power ). Plus that Pssh is no longer noticeable. Wondering if DV is an issue was going to upgrade GFB DV+ but want to figure this out first.
Car start fine , drives “ normal “ city but mashing gas it seems to not pull as it did.

I'll have my money on a boost hose leak or Boost hose blown off on the Hotside * That is where i would start! Good and update when problem has been resolved!

Thanks ... I will update. Would you suggest double up on clamps ?

I doubled up* on the clamps and used Hair spray as an adhesive after my hoses kept blowing off on the Hotside with my BT. No issues since*

Well , seems like I corrected issue after DOUBLE up on clamps ( both sides ) .
Boost is back , but will change charge pipes ( ordered ) ... noticed the OEM are very soft so they will be swapped out. Used T bar clamps .

@TyphoonFiST Thanks a bunch.
