Ok so yess my car always seams to have an issue, well more likely it is just me.
Some time ago, my car started exhibiting strange surge/stumble at low rpm opening and high boost, say 12 psi at 3000 rpm, this is with teh gizzmo boost controller.
NOW went to my mechanic, after i spent 4 months looking for issues, and couldn't get anywhere. Was told it was my coils, new splitfires. So i had them sent under waranty for check, subsequantly they were found to be faulty, 4 off, and replaced with a new set.
So i installed these last night, all well and good, but the car seams to strugle with boost not, well not strugle, but below 4500 rom, i will not see more then 10 psi, R32 actuator, and then abve 4500 rpm, the boost goes up rather fast to preset boost setting on the gizzmo.
Now i think my car feels flat below the 4500 rpm range, so perhaps my VCT is not working, allthough consult does not report a fault, is there any way to check the VCT other then unpluging it and see if it makes a differance.
What else could couse this issue?
Thanks, and please this is rather urgent, as i need to get my car soughted before the new turbo goes on.
