Texas GN
Jack, just bought a 1987 25k GN that has been in a warehouse for many years here in San Antonio Tx. The car has had a few mods on it but i think for the most part it is stock. The mods are dual exhaust 2.25 ,headers, gauges (boost,temp,oil pressure,temp) hypertech chip (PT# 41 373). Can't seam to find any info on a 41 373 but there is plenty of info on the 41 372. I changed the gas tank out because it was full of rust and changed the fuel pump to a Walbro 255lph.
Oh, one other thing I have a hot wire kit for it too. I noticed it is running lean, the plugs were very clean; to clean even after 500 miles. Anyways I would like to get the car into the hi 12s low 13s. I need you to put me on the right track, you said something about 42lb injectors and a chip? Can i use the chip i have? Are the Valve springs up to the tasks? I hear they were weak too. Thank again, Glen
