    what were your before/after dyno #'s? Your combo is exactly how mine was when I dyno'd, except my tune was a canned SCT tune.

    All of that for only 47hp? Shouldn't you have gotten more out of that whole combo or are other people just inflating their numbers?:shrug:

    sounds to me like most people are getting exhaust setups for sound the add HP is a bonus. If what everyone says is true then out of the 47HP 5-10 came from the JBA LT's, right? Those numbers sound about right.

    My baseline dyno numbers were 261.5 hp & 275.3 tq. I think a lot of the advertised gains are subject to the other installed mods. If you add all the supposed gains for each of my mods individually, it would be more than 47. Keep in mind though, this is only a 91 tune. I do have a 93 tune coming and that will put the overall gains over 50 hp/tq. Would have been much easier and cheaper to gain that and much more with nitrous, but this is always there, and my mpg at a 55 mph cruise is now 32 mpg.
