Ok, I am getting an 86 GT. It has speed density. For some reason, I'm really feeling the speed density set-up. I mean I really like it. Now I've never owned a speed density vehicle before yet I am aware of all the complaints people have against it. My question is this: what makes MAF better than speed density? I know how each operates. I just want to know why people feel that MAF is better. I have heard that if you do a HCI combo on a Speed Density car the engine won't run correctly and you'd have to get it tuned. But if you did the same combo on a MAF car you would also have to get it tuned right? Both systems require tuning for modifications so why is MAF the preferred system?

Unless you add a huge cam and hogged out heads, the mass-air ECM will adapt pretty well without tuning. Most speed density cars have idle issues just adding a small cam. On the other hand, if you have two stock cars, one speed density and the other mass air, the speed density car is usually more responsive.

pick the right cam for a speed density ride and you'll be fine

I agree whole heartly with mjr46.You have to sometimes agjust the idling and timing but i've had great sucess with my current set up.The best part is for ever I heard you can't put a cam in a speed density car without converting it to mass air .WRONG!!!! I' m planning on putting up a small video of my car idling on you tube soon.
