Good news! I fixed my slow acceleration by switching out the 660s back to my stock 450s. I'll wait till I head back to the shop to get it tuned to put the 660s back in.
However, I'm noticing that I am getting an exhaust leak right where the exhaust manifold meets the turbo. I could see the black smoke deposits around the edges. All the bolts seems to be tight. The exhaust manifold is my stock 2g ported to a 7cm with that hard metal 7cm gasket plate. What's the best way to fix this "one of my many dsm problems"??
