thanks everyone i think i got my Christmas present haha

 

Why not just see what kind of price your muffler shop will give you? If it's more then the jeg's y pipe, just buy it from jeg's and have your shop modify it to fit your rig.

 

now if i order the sct tuner from that hemifieverything.com does it come preloaded because i was reading thedescription and stuff and it said to verify the pcm p/n ....i dont want to pay 260 bucks for somthing thats not going to work

 

Yep, comes with three tunes.

 

do u happen to know what the three tunes are lol like what each one does

 

Tunes vary by the octane of gas they require. There is 87, which is basically an improved "stock" tune, that also gets rid of 'torque management'. A noticeable improvement over stock, with little to no impact on fuel economy. (once you stop abusing the go-pedal playing with your new-found power.) 91 tune, that is a bit more aggressive, and 94, which is even more so.

That is a VERY basic interpretation. For really good info, call or email hemifever, and have a chat with him.

 

ok cool bc ill prob just run 87 octane unless i start to do more mods.............i think this is the one i should get http://www.hemifevertuning.com/Produ...-Can-Tune-Only

 

That's JUST the tunes though, no tuner. (that's the software, but, you need to hardware, the tuner, to actually upload it to the PCM)

 

ok so i need to get this one i think it has the software and the actual device http://www.hemifevertuning.com/Produ...ctCode=SCT-Can

 

Also, it changes the shift points in the transmission so that it shifts earlier like 2/3 throttle instead of almost full throttle, a much needed adjustment, and moves overdrive to like 53mph instead of 45.
The 87 was slight improvement for me as it removed the death flash
I haven't used the 91 tune cause my mid grade fuel in WA is 89 and would probably cause pinging.
The 93 tune has an obvious power improvement and that's the one I run. Very happy with the Hemifever SCT
