2lt hard to get over 80km

Post by sldwys »

[quote="sldwys"]Hey all - I have searched and searched again and everything i have found I have tried ... but nothing seems to fix my problem.
The problem I am having is... Lack of power after 2/3 gear.
Manual 5 speed btw.
Turbo boosts at 9psi with 3" exhaust, Snorkel, wastegate washer mod.
Green light on for turbo, Never goes red.
Have checked all the air lines and all seems fine, Fuel filter been replaced.
Red VSV valve has a broken air nipple off it, And theres a steel pipe by the turbo thats open to atmo.
After some reading I found the Boost compensator is supposed to be hooked up to the same air feed as the Turbo pressure switch by the airbox. So I done this at it seems to of gotten... better but not great yet. although upon doing this the truck is smoking alot more than it was before so maybe over fuelling now ? 4 and 5 gear are still... underfuelled from the feeling.
Alot of the airlines in the enging bay are not where they should be from standard... But even from looking at the airline diagrams I cant figure out what is supposed to go where and how can i bypass the broken VSV valve ?
Please help... I am almost at the end of my tether!

thanks.
