R34 Help Over Boosting And Dont Know Why

[gttiwanna]

There isn't one goin to the ebc just the stock gauge boost sensor and I was driving to work this morning and still the same so must of been the hot weather that made the boost come down so would that be an air/ fuel thing goin on ? Maybe that's out and making the boost go u?

mate. take it to a shop.

constantly driving a car that is overboosting and you dont know why is dangerous territory. For the turbo and the motor.

A decent shop can prob look under the hood and easily see what is incorrect and sort it for you.

Also, as im not sure what boost gauge you have been going off in assuming your car is overboosting. But the stock dash gauge is not accurate, nor reliable. Especially at the age of these cars. (mine use to read about 11psi when in fact i was at 14-15psi)

good luck

Lol yer boarder line taking it to the shop and the gauge is a defi unit from Japan not cheap shit hooked up to the fpr as specs says to do friend has a wideband so mite hook that up first and haven't been over boosting it all the time been pussy footing it round for to long now lol

maybe try getting a cheap shitty gauge to try. one that isn't an eletric gauge or anything. just simply mechanical gauge. see what that shows the boost as being.

I have lol had one laying around

But my question now is how far does the wastegate flap open on full boost is reached and gases are going thru ?? Mine look like it opens about 50deg is that about rite ?

Ok now this is weird went for a drive boosted the shit outta it and the boost went up then back down so it can't be boost creep must be spiking but where ?

[gttiwanna]

If anyone needs to know I advanced the timming a bit and came good holds boost fine now

[jjman]

'a bit'? How many degrees is it at now and how on earth did it change from what it was set to originally?

RIP GTT

It's about 17 degrees now and have no idea how it changed or if it ever did I moved the cas a lil bit and went for a drive and it was good then checked it after a day or so coz I didn't have a timming light but don't care runs good I'm happy
