ok Guys, im new to the forum and the GN scene as well. I helping a friend work on his 87 GN. Let me just start by saying that he bought the car about 8 months ago and about 5 minutes after he hands over the cash he asks if i want to drive. So of course i took him up on it. Well went WOT for aprox 3-5 sec on 15lbs, we had no real reason not to trust the tune it was previous owners daily, but live and learn i sent both head gaskets into the valley. We studded it and had ne guides and some mild porting done.
About a month ago the car started showing more knock on SM than usual and even noticiable detonation and without any computer interface into the car we could not establish why. so i talked him into XFI. I am mostly a mustang guy and have built and tuned from scratch a MS2 system on a boosted 351. But that was on a spare car and this is his daily driver. So i am looking for a base tune if anyone has one..
I do know we should have picked up all the Stuff from Hartline as he seems to have a very good rep and it would have come with the start up files. But we didnt do the research and didnt think much of it when we ordered it. Now my VE numbers all seem way to high i cant find much info to tune the spark table. We are running the Caspers box. Face palm.......
Car has a precision turbo(not sure which one but have seen it make 30 lbs)
larger intercooler- not sure what you guys call it, its located in stock location but ram air fed
mildly ported heads-studs
Meth injection but its seems they all do.
Siemens 60lbs injectors
Any help will be greatly appreciated.
