question on turbo

[187_teg]

I have an 95 integra with t3/t4 turbo set up on it with chipped ECU. I was wondering ever time I i am racing and i hit second gear my car jerks real bad like it boggs then picks back up. i dont know what is wrong with it I thought it was my BOV that when I switch into second my BOV didnt release the air fast enough so it hits the intake mani I can adjust it but i thought i would ask opions about it first. another person said it could be my ecu its a chipped ls. but i dont know. does anybody have any idea what might be wrong?

give us more details about your setup. Did you buy the car with the turbo on it? What fuel management are you using?

[turbteg]

well its a bone stock ls motor I have a HKS ssq bov turbonetics wastegate t3/t4 turbo front mount dont know what kind for fuel management I only have a inline fuel pump i pulls real good 13.9's in the 1/4 I think i could do better if i could fix the problem. anything would help do you need to know anything else

you really need a wideband 02 sensor sounds like your probably running too rich after a shift.

where did you get your "chipped ecu"??? lots of times the same setup will require a different tune. how much boost are you running? you really need to know what kinda fuel management your using i'd bet you gonna find a solution to your problem there.

i'm only running 6 psi. It happens real quick it jerks like it goes into a dive and
and picks back up in boost lag. it happens as soon as i it 2nd gear. I heard
that if u unplug your speedometer ot odometer sensor or it goes bad that your car starts running rich cause mine dosent work i havent had time to see if its unplugged or not is that true if so do you think thats is whats wrong with it

tdi hatch is me too i keep forgetting

What it seems like is that you are loosing wayyyy too much boost when u are shifting gears, you need to do something with ur fuel managment to still dump a little bit of fuel in ur engine when changing gears... i had a stand alone fuel managment and i was able to adjust the fuel rate in between shifting gears. If you are un able to do that, then maybe u should try tightning up your blow off valve spring so u can still keep enough pressure to make the turbo keep spooling.

I tried tightening the blow off valve and it works good thanx for the help
