Full bost but poor running.

Mind if i pick your brain?

Full boost and excellent vacumme and i have a problem.

Car runs fine on tick over.
Boost up in 1st and 2nd gear excellent
3rd, 4th and 5th is where the problem beings its a bit lumpy comming on to the boost and when it hits 22psi it flutters 1mm each way on the gauge. And will pull but lumpy and not as quick and as smoothe as its normal self it also whistles alittle when sucking air and small cats and dogs.

Now i have cleaned the isv valve (really gave it a good clean) because the car was stalling in some way?

The isv works alot better now but if you come off a hard run it will just stall (only when you have had the turbo going)

This has only happened since fitting the samco hoses.
I have also turned my forge Dv around the correct way as i had it in reverse prior to the new hoses

Any help would be very much appreciated James

A long shot but make sure the connections on the MAF are clean, and also the hose on to the MAF is air tight. I had a simialr problem and newsh sorted it for me by connectinf the MAF hose properly and cleaning the connectors. Hope that solves it mate
