mad bogging
 

sometimes when i start off in my car it boggs so much like it starts going and then boggs and throws you forward and tehn finally picks up and starts going. also ive heard that it is better to vent your bov back in to the intake of the turbo instead of the atmosphere craeting less lag

do you have a cel? have you done a tune up? is one of your injectors out? too much fuel possibly?

Re:mad bogging
 

Yeah, I just read that in sport compact mag. It has an article on blow off valves. You should read it, I will read it again but I think it says if you route too much back in it can cause damage to the turbo unless it is a ball bearing type of turbo.

This doesnt happen ur first time of boost does it, (like every time you shut ur car off and start it it stops until you boost agian), its the map sensor picking up boost, you need some check valves or a missing link check valve.

Re:mad bogging
 

i have 4 check valves and it bleeds off all the pressure, i checked it. i only happens when i start my car up after its been sitting for hours.

Re:mad bogging
 

let your car warm up before you start dipping into boost. Your ecu is adding extra fuel because the engine is cold.

Re:mad bogging
 

hmmm...im thinking too much fuel...try putting a bleeder on the line to the fmu....this is just an idea, does it run rich?

Re:mad bogging
 

its too much gas. :P

Re:mad bogging
 

when i start off i dont hit boost i just take it easy till its warmed up....and it still bogs with only a little gas applied

Re:mad bogging
 

your base fuel pressure might be too high....?
