hey guys my buddy owns a 03 with the 4.7. hes looking to get more power he has shortiees and k&n and cat back.

i have a sct tuner for my 5.9, i was wondering whats avalible for the 4.7 for the year range of 2003 and whats worth it for the power ? i dunno if superchips would be the way to go and what part # ? is the gain with the tuner worth the investment to wake up the 4.7 ?
thanks in advance

 

ive got the 3715 model and love it it gets rid of the 100mph speed limiter and makes a little difference in mpgs too, there is also the flashpaq 3965 model? that'll work that has all the fancy 1/4mi timer and extra tunes as well

 

how the take off power compaired to stock ?

 

i think i tested my 0-60 time before and i believe it gave me a half a second decrease in time

 

if you buy a new s.c, its better deal to get a hemifever tune. if you find a used sc 3715 then i would go with that one. but i would take my sct over s.c anyday.

 

ah sweet that what ui like to hear ! ! i have sct also and had superchips ! sct made a huge diffrence over superchips. is the same price 265 for you guys ? and contact hemifever ? www.hemifevertuning.com ?

 

same price same email. you got it.
