My friends dad who is a diesel mechanic says that if i chip my gt i should get around 35 more hp but only if i get a new throttle body because of some limiter sensor or whatever. Is this true?

 

well it depends on what you drive. And this doesnt go in power adder this section is for nitrous,tubos,blowers etc....

 

Well it depends on how much hp/tq you have now, if its a handheld tune or if its a custum tune, if your N/A or Forced induction. If you have a handheld tuner chip and you use the tune that is already on the chip depending if you use 87 91 or 93 octne you can get around 15- 25 hp. You will get more hp if you have forced induction than you would if you were N/A. And if you have a custom tune depending on how good the tuner is you can get a lot out of it.

 

figure you'll see maybe 10hp and any more than that is in all reality a bonus. the new TB isn't required for stock cars (cept termies) but you might pick up a little depending on your overall combo. Quit talking to your dad... talk to a mustang tuner.
