I just finished with my build on my 1991 Galant VR-4, she sat in a barn for 9 years and my buddy and I saved her before the barn fell in. Upon getting the car home the motor was taken out finding a massive crack in the block I bought a used motor and sent off to the shop to be built. Wiseco 8.5-1 pistons 1g rods, both block and head were machined. The head was fitted with all stock components. After installing everything back into the car I added a Megan racing 3-inch downpipe going into a magnaflow cat and a straight 3-inch pipe all the way to the back and a walbro 255. It has a 14b and everything is stock. Anyways, the car drives great, however when getting into boost the car breaks up and wont accelerate, the car begins to sputter but wont drop boost or die. I've changed the coilpack, ignition module, spark plugs NGK BRP7ES gaped to 25, NGK spark plug wires, MAF, Fuel pressure regulator, and installed a Hallman MBC and a autometer boost gauge, still no change on any front. Any help would be appreciated. Thanks
