strange boost problem???
on the way back from billing,
when i stuck my foot down, it would boost to just over ten psi then hold 8psi but occasionally very quickly drop to about 4 psi??
basically whats happening is the boost is fluctuating it will drop to 4-5psi then pick up again.........
as most of you know ive got a recon turbo and actuator which has just gone on and this has only been happening since.
This was the first time also i have run my car on normal unleaded as opposed to super.......... with the heat of the day and crap fuel make my boost rise and fall quickly like that??
also im running my standard sri 8 valve fuel pump..........will this be ok or is it not sufficient???
any help appreciated.........
I think you've answered most of your own questions here.
Turbos shouldn't be booted on normal unleaded. They won't blow up its just not good for them and they may retard the ignition a bit (hence the 4psi).
Not sure what the rating is on the Fuel pump but I'd be surprised if the Turbo one was the same as the 2.0 8v, might be worth changing that.
cheers matey.........just needed to hear it from someone else......
Bren is stil using the fuel pump from his 1.4spi astra on his C20LET and has no problems.

Like Cem said, you've answered your own questions.
And as for the fuel pump, I'd be finding out what it can run if I was you..........
