has anyone tried these gforce chips

[z400motocross]

i was lookin around n found this link http://www.gforcechips.com/fordranger.aspx n was wondering if anyone has tried them yet cus they have a no question asked return so are they worth it.

also can someone give me the link to tom marona website i want to look at heads n throttle bodies.

ive been workin on my 99 ford ranger 3.0 n have been tryin to figure out some things to do to it performance wise any suggestions? i have a glasspack muffler,ram air intake,throttle body spacer. im bout to buy the 4/5 in drop kit, and m putting in bucket seats from a mustang. so any ideas?

are jba headers worth the money?
