going from f13 to t-rex, is it worth it?
going from f13 to t-rex, is it worth it? after hearing about the t-rex so much, i'm thinking about trying it. do you guys think it is worth the swap? will the f13 tune be ok to run with it? i have stock heads with all bolt ons and 4:30's. see sig for other mods. thanks.
depends on your goals for the car
If you daily drive i wouldnt really bother. your putting 390 rhwp the t-rex might add 30. I think you would get better results w/ new heads realistically

To answer your other question, your F-13 tune will not work for the T-Rex. It's an entirely different animal and takes exceptional tuning skill to make it enjoyable as a daily driver.

For a max effort drag car, the T-Rex is at the top of the heap. An F-13 tune will get you in the ballpark, but for best all-round power, you'll go fastest with a speed density tune and no MAF. Now THAT takes a little tuning skill.
