I achieved increased performance from my 088 by wrapping the crossover/up-pipes with header wrap, running 4" exhaust from downpipe back, and I have a K&N in the ATS airbox. Being non-wastegated, it's always going to have low boost in the low RPMs. It does pick up much better than it did before the mods, and can hit 11-12 psi max vs. 7-8 psi before.
