Oookay.................... I felt the fart sound between shifts was ridiculous and overall I wasn't as happy as I thought I'd be when I bought it. And I'm truly happy to have the stock exhaust system back on. Bottom line, your Jeep, your money, do whatever you like.

Funny, the torque management between shifts in sport mode is what I like. Reminds me of a Maserati between shifts....

Re: HemiFever vs. DiabloSport tunes

Sounds like you have the wrong expectations for the vehicle. Try removing the interior then run it down the strip again.

Not sure I understand what you're saying, care to explain?

Basically he's calling you a [insert whatever you want here] for trying to make a Grand Cherokee a race car...when in fact we're simply trying to up the performance, and inform the public on what works, what doesn't.

Lots of negativity, and one of the reasons why I hate the internet.

Re: HemiFever vs. DiabloSport tunes

DrSpeed and Sweed,
Thank you for clarifying and you guys are correct. I have a 5.7L Hemi engine and I'm trying to get more performance out of it. And going to the dyno and dragstrip are the only two ways telling me if the modifications I added did in fact increase HP, TQ or if the vehicle got any faster.

For what's its worth, removing weight is like adding more HP but I don't plan on driving my Jeep with no interior in it, so no need to test that. For those who are curious, you can read all about it here: http://www.tuneruniversity.com/blog/...-weight-ratio/


Thanks again
Michael Plummer

I'm all for maximizing the performance on my Jeep as well, I want supercharger but it's too expensive at the moment.

Airfilter, exhaust and Hemifever tune have to work for awhile. Too me it's a big difference between the diablo sport and Hemifever tunes with my favorite being Hemifever, I just wish it had a little higher top speed, with my Eibach springs and SRT wheels it's pretty fun in higher speeds

Can you post a picture or two of your Jeep with the springs and SRT wheels.

Thanks

I take better picture this weekend, I love how it rides now, stiffer with much better high speed control but not too stiff, it's perfect to me.

Perhaps Sweed is on to something here - although dyno graphs (area under the curve) says something, perhaps Hemifever improves the driveability of the vehicle....

I was just goofing with ya. up for having fun with your truck. Aside from the paper power band it would be helpful to hear about the difference between the tunes, drive ability and such
