Should I buy hypertech programmer for $200?

Depends, if it is still "married" to his old GT then it is just good for keeping papers from blowing off your desk...

If it is not still married to his old GT, it is still a Hypertech :notnice:

Save up another $150 and get an SCT Xcal2 for $350.
 
I dont know much about the hypertech for the mustang. but it did little to nothing for the f-bodies.

the sct2 will grow with you. you can go to a dyno and have the car flashed with a custom made tube at anytime.

for this reason and the track record of hypertech products for other car i would buy the sct2
 
not for $200. go $150 tops.

the hyperteck does not do as much as the diablo or sct.

you can get used diablo's off ebay for $250 and it will turn off you traction control, diable rear o2's, datalog, etc. way more features.

the sct can even be upgraded to the pro racer package.
