I went up to see my friend, Todd at A&C Performance in Murrieta and did a couple dyno pulls.  Todd did my baseline pulls in Jan of this year and he did my headers, pulley and HP Tune so I wanted to compare stock vs headers/tune vs heads/cam/headers.  I have the numbers in SAE and STD.  Other than the heads and cam I am also running a K&N air filter, the 2015 throttle bodies (76mm each vs 73mm each for 13/14 style) and am running ARH headers with cats, stock mufflers, Ipsco under drive pulley and am on 91 octane. 


2014 Viper GTS, 100k+
Arrow stage 2 package, 14k+
Watching Andy look for for a second oh shoot handle on our test drive in Houston, priceless....
