I Have 97 gst with apexi 3 inch downpipe and N1 exhaust, Injen intake. My next mod is either goign to be to buy gauges and a hallman pro manual boost contoler. This will run me about 320 bucks or buy the greddy intercooler piping for like 205. What would u do first. Also about how much of a increase will isee from raising 2 psi boost or from the intercooler piping.
