Is My truck ready for B.B.Tune ?

[Travieso]

for does of you who have a tune should i wait on the tune till i get my long tube headers or should i just do it now?

1.What's the difference between a 87-91 tune ? (HP Wise)

2.anything else i need to know about before getting this tune ?

well you get free retunes, and if you plan to do LT headers, you may plan on 02 sensor delete. So if headers are very soon, wait. But it was a mod I sure wished I would have done sooner.
IMHO, do the 91 octane (or is it 93) but I run on 91. The power is better, and the gas milege debate between running 87 and paying for 91 at fillup are minimal at best. Do the higher octane.
