Power Lose

[rich1377]

OK i have a couple questions to see if anybody can help me with.

first off i drive a 93 Tsi with the JDM Cyclone swap

OK my car like in the mornings or cold nights boosts really well but once the car warms up its doesn't boost as well.

and also on a normal day basis my car with spool up just as normal but the car doesn't really move like it should. sometimes the turbo will spool up and the car just seems like its rejecting air or something it really hesitates. and sometimes it will do just fine. so i have a bad boost problem somewere. also the car has kind of a slight studder in the idle kinda of like a miss, but i have changed my plugs and tried new wires and that doesn't solve that problem. I gapped my plugs to .028 and i actually have a FMIC on my car and all 2.5" aluminum intercooler piping upper and lower. but i have noticed that a while back when i washed under my hood(covering up the important things)i noticed that a little water got a down in my plug wells, but i was able to get most of it dryed out, so i need to replace my valve cover gasket to fix that but i don't think that is my problem with the studdering. i probably have a boost leak somewere cause as of lately i can here it leaking through my boost gauge inside the car. but then again i am losing alot of power and i don't think a boost leak could be the cause of all the power lose. some one told me that there are some kind of air or coolant sensors that could be bad. i already replaced my MAF

So if someone could help me with these problems i would greatly appreciate it.

Thanks!

if you're running the cyclone intake manifold, that could be a problem.

do a compression test.

do a leakdown test.

do a boost leak test.

replace your plugs and gap them again to .028.

check your ignition coil pack (via manual, should have a set resistance between 1-4 and 2-3)

check your resistor plug.

check your wires.

check your turbo for shaft play.

replace your fuel filter.

replace your fuel pump.

check your timing.

check your CAS.

I could go on for days...

What are you using to open and close the secondary runners on the Cyclone manifold?

i am just using the standard cyclone intake that came with the motor when i ordered it. And i have no clue on the secondary runners, the motor never came with the actulator to run them i believe. Today when i was driving i stepped on it and the boost gauge registered boost and you could hear the turbo, but the car was like at a stand still pretty much it drove like it had no turbo at all, and some days it will be just fine it will boost and spool up great.
