I'm really trying to be nice. But you insist on going there...
Maybe YOU should get some REAL WORLD experience instead of spewing crap you read in a magazine verbatim.

****, you can't even get that right....
Furthermore, that's NOT what the magazine said. It said NOTHING about speed density. I have the mag.
Speed density, only availble in 87 and 88 fox 5.0s, is NOT what you want- when you starting modding an 87 or 88, you convert to MASS AIR. No one converts TO speed density. Tell you what, go through a set of heads, a cam, and an intake on a speed density car and report back.
But thats neither here nor there and has nothing to do with 94-95 cars. Like I said, you are VERY confused here...what the article DID say was that the 94-95 specific ECU does not accept bolt-on modifications. Which is total BS, which you'd know if you had real world experience with these cars like myself and most others here in this forum.
My own 95 GT has a bunch of bolt-ons, has gone 13.3 and 106 MPH, and likely will go high 12s this year on the stock ECU with the stock tune...
Yeah, the A9L in the 89-93 foxes is easy to tune with, but you won't hit issues with the 94-95 computer until you either put a radical cam in or run big injectors...neither of which this guy said he planned on doing.
Therefore, he doesn't need "The computer custom tuned ".
Do a search of this forum regarding that POS article. There's plenty of info here.
People tend to like heros better than those who spread utter MISinformation when someone's looking for help.
