From my understanding, the HEMI isn't too fond of iridium or platinum plugs. I'm sure others will chime in.

 

Cooler 180 tstat works well on the HEMI With the Tune
I am going to use the Mopar Plugs
STEVE

 

Also, aside from the 180 degree TStat, there is a bigger throttle body you can purchase directly through the hemifever website that will also help quite a bit.

 

I changed my Tstat in my Magnum to a 180 but only changed the plugs when I did internal motor work. For now I'm going to hold of on the Tstat for the D. As far as the bigger TB I looked on Hemifever's website and I'm not seeing anything. For now I'm waiting for JBA to release their set of shorty headers and mids. That should really give us a nice little boost and increase in MPG. Speaking of I'm still stunned how much better my gas mileage is. It goes into MDS so much more now and stays there. It never kicked in this much stock or with the canned Diablo tune. With an increase of over 2 MPG it will be paid for by the end of the year.

 

You just gotta look a little bit. It's under "Tuning Compliments".

Say hello to the "Little People" they might help!!

 

Wondering why budoboy had so little difference with his hemi fever tune? And he actually tracked his D...and has hard numbers to prove not much changed...

You make it sound like he got a placebo and you got the real thing

Budoboy any updates? Did any tune revisions from hemifever net you any better results?

I really like numbers and dyno charts or data logs they tell better stories

 

Unless all you're really saying is that driveability went up but performance not so much?

 

You try driving in the tow/haul mode? It kicks down faster on inclines.

 

I went back to 87 octane Diablo sport tune for a while and although there isn't much acceleration difference if any, the hemi fever tune does feel better as far as shifting goes
