#'s Definitely seem low. See what Brenspeed says. You might want to look at getting it dyno tuned.

Did Brenspeed account for the elevation in CO in their tune? Did the dyno tech record your AFR? Did he data log at all while on the dyno? If he did, send the datalog to Brenspeed and have them modify the tune. They might even be able to modify your tune off of the dyno graph as long as it displays AFR.

The thin air up here is definately not as friendly to N/A mods as it is F/I, but I would expect to be making better numbers with what you have.

id go to a dynojet if you want numbers. if you want to see how the tune is, a dyno dynamic is great. just dyno dynamic leaves more room for user error (virtually every dynojet will read very close to one another depending on temp, humidity, etc) plus it reads lower.

i was trying to locate your info ! whats up , hey i want a second opinion , where did you get your car dynoed at?? and ya i think brenspeed did account for elevation because im told im here in denver where its a mile high... and as far as downloading my graph to here...it seems like i have up load this to photobucket or something then submit it?

looks a little lean at 4 k , but heard that usually ok for canned tunes

I would send that sheet to Brenspeed and see what they have to say, it looks pretty consistent at 13 - 13.5:1 which in my opinion is a bit lean but I could be wrong I'm not a tune guy.
