I finally got my dyno results back... (via e-mail). Can I get someone who's really good with reading them and have them discern what are the pros and cons to this XFI NSR Comp Cams Stage II.. Please note, the first pulls were bad.. I had a faulty spark plug.. and you can see where they replaced 1, and then where they replaced all of them...
This Is ALL of my pulls

and this is just my final


I also have the text format, if you guys are wondering just how far or high it is at any one point

Good #'s. I was looking into getting these. Do you know how much power you gained just from the cams? Also how is the seat of the pants feel after the cams. Lastly......idle???

slowstang06

~25rwhp from the cams. Obviously, my opinion on seat of the pants would be biased since, according to the dyno, i had been riding around at under 250rwhp (since that was including the LTs and X and cam) but lmao, 325 is niice tap the gas and you need a tissue if you know what i mean ;] Idle actually isnt bad w/ this cam, its fairly mild, you wont hear it unless the engine has been warmed up then it will go, it sounds beautiful with the MAC LTs, Bassani catted X, and muffler deletes... Makes the whole car shake at the stop light and then you can hear the lope... If you want a really loud one get a THUMPR but I heard they are really really weak in the low end

ScremnS281

How many miles on the plugs that were bad?

slowstang06

18.5k miles...

Nuke

Sweet. Gotta love seeing numbers like that.

slowstang06

i still find it hilarious that i was under 250rwhp with SCT 93 tune, JLT CAI, and an O/r H

09blkgtcal

can you let us know what effect the cams had on mpg

mygt500

Thanks for posting and I think it looks great from the tuning standpoint (A/F ratio etc) I had my guess backwards (original guess was 315 HP and 325 TQ)
yours are pretty much reversed! congrats again!

slowstang06

not tooo horrible.. i probably was avg 17-18mpg before (4.10s) and now im at 16-17mpg (but i have seen as low as 14) the only time gas really is lost really negatively is at idle for some reason...

and thanks. i honestly wasnt expecting it much either, not from a no valve spring cam, that was basically just a swap out of the stock one
