on my wife's
Jeep Grand Cherokee High-Output V-8 (265HP) based on my limited driving experience of less than 200 miles. [8D] [8)]
I had my wife's vehicle "performance chipped" last week, and, in addition to noticing more power, there was a solid 10% increase in fuel ecomony for the first tank fill-up of premium gas today.
While it is still way to early to draw any firm conclusions it does look promising that the Jet Performance Chip is a "winner". Check-out their site here: http://www.jetchip.com/
My
initial impressions (some city/mostly highway) are as follows:
* For the money, this performance upgrade is cost effective. For $218.90 installed including tax (MSRP is $300) my wife's Jeep may well have gained around 30HP (with K&N drop-in performance air filter) bringing the total horses pushing the vehicle to 300--just 40 short of the new Chrysler 300C HEMI. Overall, the estimated horse power gain is said to be somewhere around 10% for most vehicles (conservative estimate according to the Parts Manager at my
DC Dealership).
* There is a noticeable improvement in low-end torque.
* Less movement depressing the gas pedal is now needed to attain comparable speed than before.
* The exhaust tone, while not loud, seems to have changed somewhat to a "more aggressive/throaty sound" (with the stock muffler) especially when at WOT.
* The over-all shifting of the automatic transmission is even smoother than before--especially noticeable at 45MPH+ when in a "passing mode".
* The Jeep continues to perform flawlessly with the new performance chip--no problems noted at all.
* The information that came with the chip indicated it will provide "improved economy". Only time will tell, but my initial impressions as mentioned earlier are positive. Overall, I really like this MOD on my wife's vehicle. But, even MORE IMPORTANT, is that she is happy with the performance modification!
Guess you all know how important the Wife Acceptance Factor (WAF) is when buying or making changes to your wife's automobile.
Now, you are probably wondering...Is the JET Performance Chip available for the PT Cruiser??? Well, if you check their website under "Domestics"...IT IS NOT...at least not yet.
[:I] However, I found the following on the site indicating it is available at least for 2002 models...[:I] [:I]
"Hi I have installed a Jet power control unit on my 2002 PT Cruiser and after a dyno test i have gained 8hp with the use of your product I thank you guys for working so hard on making after market performance parts for so may kinds of cars and truck keep up the Fantastic work !! I am sending you pictures of my PT." Dean 2003/03/31
On the downside, I just ordered my Stage 1 Upgrade for my GT last week prior to "chipping" my wife's Jeep--so I'm committed to receiving a performance upgrade for my car (with comparable HP gains) but at more than twice the price. [B)] [?]
