Hi guys, my 94 850 T5 had a full service last week but I have noticed a sluggish response since. The turbo doesn't seem to boost up like it used to so I am wondering what could be the problem. I know they changed the plugs but not sure what they replaced them with. Could a different none Volvo plug affect the performance. I have the Rica re map and have done 240000 K's.
Anyone any ideas?
Thanks,
Hi. The plugs dont make that much of a differance in performance wotever make you use. Only better fuel ecom or response IMO. Might be worth checking the air filter box is on right and the air filter is in correctly. If there not this would affect the air flow........
Make sure they havent knocked one of the hoses off :)
More than likely not replaced the bcs connector is they've had the airbox off, that will give you base boost.
They haven't done a software update have they and then reversed it back to stock map? Just a thought?
Wots the bcs connector please bud.....Quote:
