Boost Gremlins

[Spook33]

Hi Guys,

Need a little Help

CAR 96 R33 GTS-t

mods

3 inch cat back exhurst

K&N Pod

BlITZ BOV

Turbotech Boost controller (hole in back) approx 10 psi installed 3-4 months ago

Problem

over the last 1 to 2 months have noticed that when i plant my foot stock boost gage climbs and holds at arount 10 psi as it should but only pulls hard to about 3.5 grand then seems to be holding back for some reason? it would still climb after 3.5 but rather slow ???

thought it could be my imagination or some thing then i had my car serviced last week.

now car is doing the same thing but much worse it comes on boost and pulls hard to 3 grand then nothing ??

whats wrong??

have done a search could it possibly be the ECU going into rich and retard mode??

or has the boost controller turned faulty

any thoughts wouldl be much appreciated.

dunno, but i should have copywritten my username

rich and retard mode is a violent cut off.

you could try resetting the ecu. also if you still have the stock boost solenoid, hook it back up and take your boost controller off and see if it still does it.

i removed the boost controller and now the car seems to be fine.

hopefully it was just that as i was thinking maybe it was the clutch sliping.

back to stock boost

[mad082]

if it was the clutch slipping the revs would rise but the speed wouldn't change.

more than likely it was something wrong with the boost controller.

The stock boost gauge doesnt go to 10 psi. Only 7

Anyway, try replacing your boost controller with a friends one that works fine in their car?

It could be a number of things, from fuel flow (fuel pump, computer) to ignition (coil packs, spark plugs). Your mechanic should have noticed the problem and diagnosed it when he completed the service???

the stock boost gauge isn't in psi. its in mercury. 7 on it is about 15psi (bit less).
