hi,
when im launching from; lets say 2000rpm, all the way till 6000 i only get a rate of 2psi on my boostgauge.
my wg is set @ 4,5 psi.
in 2nd gear i do get 4,5 psi also in 4rd.. ect..

i have 70mm coldside chargepies. its kinda oversized, can this be the problem?
or is it possible that my BOV stays open?
of i have a boost leak ?!

plz help

low load condition. i always got lower boost in 1st gear

taiajam

thats gay, how can this be fixed?
im going for 10 psi, and all those psi's are needed in 1st gear ofcourse ^^

i was running 10 psi and would never get over 6 in 1st

its the nature of the beast. you'll never hit as much boost punching it from first as you would from a fifth gear roll.

ok, so its a fact every turbo engine has lessboost in 1st gear.
but there's always something to make is a little more.

how slow does boost build? If the car feels NA then the wastegate is most likely not closing all the way. If you can feel the turbo actually spool its probably alright.

I'm running a smaller sized turbo and it can build full boost in 1st, but by the time the boost gets up there it's allready boucing off the rev limiter, tires lit up and time to shift.

in 1st gear, it feels like i have lots of turbolagg and backpressure

also ive hooked up a missinglink yesterday, but now it idles terribly rich, and it seems like the mapsensor is freaking out.
i have an a/f gaug on the narrowband lambda sensor. before i installed the ML the a/f gauge was pendeling. now its in green all the time.
