hemi is way more efficient. i get about 10 mpg. and they could use the selling point of the "hemi" badging. even though its not really a hemi.

 

with my superchips im getting close to 14mpg avg on the 87 tune, was getting around 11mpg avg before the tune.
and when i floor it goin 80 it just never seems to run out of power now! plus it fixed my speedo...

as for the lights behind the grille, if i remember right i think dirty dog did a great diy write up on it. cant seem to find it right now, just use the search box

 

i use nothing but the performance tune. never even tried the 87 tune.i got my 3815 for performance not mpg's.

 

x 2 on that one lol hell if they had a higher tune it def will get it! but went straight to 91 performance tune when i got it .....def got this for extra performance edge

 

I just installed SP 3815 in my Hemi and I have to say you can defineatly feel the difference. It runs better,shifts better,sounds better,smells better,looks better I think it even fixed my alignment . Seriously I have put tuners on allot of rice burners and I have never noticed such a night and day difference than I did with my truck this morning. Well worth every penny...

 

Same here and I look forward to getting more go fast goodies.

Hey guys, will the superchips tuner be recommended for the 5.9 with a paxton sn93 installed?
If not, what tuner should I use?

Thanks.

 

Somebody correct me if I'm wrong but I say go with SCT.

johnny

 

it says in my instructions that the superchips tuner is recommended for stock engines only

 

you cannt run "canned tunes" with a supercharger. you will be to lean. you need to get a custum tune. like the sct mentioned above.
