Can someone help me with this please. Had my ST225 s week now and as others have said to me on the previous page if it boosts to near the red it's mapped but the old guy I purchased it off who had it from new says its standard!
It's crap in 1st gear and doesn't boost much but then in 2nd upwards it goes to near the top more so in 5th and 6th. But today driving it it was only boosting to half way at some points
![Confused :confused: :confused:](/styles/default/xenforo/vbSmilies/Normal/confused.gif)
I just can't see it being mapped as it the boost shoots right up for a few seconds and stays there but the power dies so I have to change gear at around 4k revs as even though the needle stays up on the gauge the boost goes quickly and it almost feels like it's just dragging along with no power from 4k revs+ in 2nd, 3rd and 4th.
Can it be a faulty boost solenoid? The only other one I had a go in before I got this was standard and that boosted to 3/4 also.
How much would it cost to get a printout of Bhp from a rolling road?
