Hello, I am in need of a reputable tuner located in the area of south jersey. My gtp is having issues oscillating between third and fourth gear at a cruise and reads a vacuum leak when I cannot find one. The car is also very sluggish after shifts even at wot as the power drops off after a shift, then takes a couple seconds to get back into power. A fellow member brought to my attention that this could all be in the tune. Mods are l36 block, top swapped, 3.29 gears with non-hd, headers, cai, 1.9 rockers, and intense mail tune. Please let me know if anyone knows the causes of these problems and if there is anyone around south jersey that I can get in contact with that can take a look at the tune and correct it if need be. Thank you.
