Can this thing really adjust your air fuel ratio? Doesn't seem like it would read to well between the MAF and wiring harness in car. Heres a link to check it out.

Also looks like its only for LS based engines but catalog says 94-02???
Link won't take you too item but its pn grn-351001.

 

I knew some people that used it on their Mustang with good results.

 

I think i would just tune the computer or have someone tune it.

 

On some other cars screwing around with the MAF is about the best they can do for tuning. For us though it is MUCH better easier and cheaper to do it right in the pcm. Not everyone has the easy pcm access we do hence MAF and fuel pressure tuning.
