Still no power under 200rpm ---But different 2.5lit D40

[xkkat]

Hi Guys I followed old Tony's words of wisdom I cleaned the MAF sensor --Replaced all vacuum lines ---Replaced the air filter and Boost control valve The violent rev rise after 2000 is gone and the car runs with less power in all gears but still dies under 2000 Whats next The turbo was obviously working with rev rise after 2000 rpm It would spin the back wheels on gravel road -in 3rd gear! - Won't do that at all now! Can't find any vac leaks More wisdom is needed !!Please regard Terry Hilton

I would be checking your turbo first before you keep throwing money a peoples guesses, could be lots of things MAP, Intercooler leak, split turbo hoses, if it was me i would be physically checking the turbo and work your way around, again i have mentioned this before but if you got the BCS off of a ebay store then good chance its dodgy (from experience)
