16 Turbo lag

[vertigo210]

I can relate with a bad boost leak.

1) Check the turbo bolts and gasket (the bolts fastening the turbo to the exhaust manifold). I once had those bolts back out and it was extremely hard to build up boost.
2) Check the upper/lower intercooler pipes (especially at the couplers). I once had the clamp on the lower IC pipe loose and it made it difficult to reach full boost.
