C20LET Boost all over the place

[Ped87]

Im having trouble with my boost when normally put your foot down it boost to 4PSI then when you change gear it will spike to 10-11PSI then hold anywhere betwen 4-10PSI

Some times will boost at 5psi then jump to 8psi and then back to 5psi with my foot hard on the throttle and not doing anything... :confused:

Anyone have any ideas?

[Graeme]

What's controlling the boost?

[Ped87]

Its all stadard still running the amal valve ive been told to remove this as it can cause this probelm...

[Graeme]

That'll be your problem

[Ped87]

Just had a bleed valve arrive so will fit that tonight and see what happens

[Graeme]

Don't go too crazy or it'll probably melt, would be an idea to keep your eye on the afr's for a bit

Agreed you need a wideband to make sure the fueling is right before messing with bleed valves .

[Ped87]

can i run the wideband off the standard 02 sensor or should i buy a kit that comes with its own sensor?

[Graeme]

A wide band always has its own sensor, if it use the factory sensor it's called a narrow band

Have a look at the aem uego nice a simple it install and use

Yeh I ve just bought a aem one quality bit of kit easy to install .
