Loss Of Power

[gazzagt4ipswich]

hello im new on here. i changed my oil and spark plugs today on my gt4 st205 and just gone to use car and it seems short of power? the apexi avcr is saying 1.1 bar boost is being reached but it dioesnt feel like it. its running smooth but short on power can anyone help please? could it be the turbo to intercooler hose that i remove to get tpo spark plugs?

Could be the turbo to intercooler hose I guess, a leak will always give you a drop in power. However, if you have a boost pressure sensor display at it's correct then it looks like you're reaching pressure.

Being as you changed the spark plugs, perhaps check them out too. Even pop the old ones back in to see if the problem goes away?

When a problem occurs after changing something, always check where you've worked as a start.

had a similar problem and it was an ignition coil tht had gone but it could easily be your ht leads or actually just the sparkplug

are you sure it's the right plugs? I've lost count of the amount of people using the wrong ones supplied by motor factors
