Installed a few new upgrades...

Hi, all.

Im not sure if this thread is going to add fuel to the fire or if anyone really even cares, BUT I thought Id post this for people like me who like to look at the numbers advertised then get a real person using that product's opinion on them. So, this is my opinion.

I installed the intake and TBody spacer about a week ago and the Jet module yeseterday.

1. K and N Air intake - I've used K and N filters for 12 years or more now and this was my first intake kit. Takes a little time but is totally do-able yourself in about an hour and a half as advertised. Here, I didn't notice quite as much power increase, but that's not honestly what I was really looking for with this piece. I felt like, if nothing else, letting the engine breathe cooler better filtered air for the entire lifespan just seems like the right thing to do. Relieve stress where possible to prolong longevity. Makes sense to me. Ill update after running it in another couple weeks.

2. Air Aid throttle body spacer - Oddly enough, the part I thought wasn't really going to do much probably gave me the most surprise. This was the first component I installed and what I first noticed was definitely a better throttle response. You hit the gas a bit and you feel it pull. One thing I wasn't aware of is it does make a slight whistle that sounds similar to a turbo. Not crazy loud, just wasn't expecting it.

3. Jet Performance Module PN 90901 - All info online initially pointed me to the wrong module. Had to return it and got the 90901. The only 2 complaints I have about this is the misleading info (and I did a LOT of research) about the correct part number and secondly, the instructions seem a bit misleading because in one section it says for a certain year range of Grand Cherokee's is in the first slot, then a different one said 3. Had to call JET to verify before I screwed something up and the correct port is the White port (#3).

That out of the way, I could also tell a definitely throttle response increase. Gun it down the on-ramp to get up to speed and it definitely feels better. Primarily what I was hoping for here was better shift points and slight MPG increase. Ive only had the thing on a day or two, so no increase yet but Ill keep my eye on it. The shiftpoints were actually way better than i was expecting. It always felt like my truck was staying in higher gears too long when downshifting and shifting very slowly from First on up. Im happy with the module all in all despite all my prep work out the window.

One other thing I may as well mention here...The videos of Jeep module installs dont make it very clear about the computer connectors so for anyone still with me thru this rant, you have to slide the red connector towards the front of the truck then push the little black springy piece down to dislodge the connector.

Overall, I am very happy with what ive done so far. It has made it funner to drive than it already was and hopefully I can increase the lifespan, have a little better performance and slight increase in mpg.

Hope this helps others later on.

P.S. Eibach lowering springs coming in on Friday

Please post before / after pics of the springs. How much are you paying to have them installed?

Re: Installed a few new upgrades...

Im still shopping around here in Seattle, but the LOWEST I've been quoted has been $700 which REALLY sucks because I dont think this is super difficult, I just dont have the place to do it myself, living at an apt with no garage etc and a sloped driveway.

Will definitely post some pics when Im done though

Re: Installed a few new upgrades...

Update time again:

After a good bit of research and not a SINGLE bad review for Hemifever tuning, I decided to bite the bullet and get a Diablosport T1000 from Hemifevertuning.com that comes with a custom tuning for the same price as the T1000 without the custom tuning from many other places. Seemed like a no brainer.

Impressions - The JET module I ran around with for a few weeks seemed cool but definitely a minor upgrade. The diablosport and first 93 oct tune Sean from Hemifever sent has blown my socks off. Im in a v6 and it feels like a small V8. I wasn't expecting 100HP increase, but it most certain gets off the line faster, better throttle response and seems like it will generally maximize every other engine based performance upgrades Ill do in the future. I also like the fact that you can save different tunings for different things. Im a pretty normal driving guy, so around Seattle, Id like a little more low to mid range grunt and when Im taking my dog out hiking or camping or something, the mpg saver tune from Diablo may be a good way to go. Haven't tried it yet but the idea is sound. I could also see other possibilities for the Mustang crowd or even Grand Cherokee SRT crowd - one tune for dragging or track and another for daily driving.

As an "in between update" I just wanted to let you all know who care that this seems like a solid purchase and has transformed the feel and pull of the truck.

Side note - I had ECM errors when I first went to install the stock diablo tune and had to call Diablosport tech support. Super strange but during the update I had to open the driver side door when it got to about 90% and that allowed it to work. Had mild heart palpitations thinking Id really screwed something up at first. After that I sent my info to Sean and he later found out there's no transmission control for my 3.6L like there is for the 5.7L Hemis. Sucks. Not sure if that will be updated on Diablo's part at some point but in case someone else is curious, these are my findings.

Re: Installed a few new upgrades...

Cool, thanks for letting us/me know. I'm in a mission to get my GC Hemi up to speed with the SRT's. I have had my eyes on the Diablo tuner but might wait until I changed everything I want to have done first.
