jet chip from website
JET Performance Products are developed at our state of the art facility in Huntington Beach, California using the latest Dynamometer Techniques and computer monitoring equipment to insure all JET chips and modules are tuned for the maximum torque and horsepower gains throughout the rpm band.
The programming changes to each JET chip are extensive and include modified spark advance tables, air fuel ratio modification, torque converter lockup (in automatics), shift improvement in electronic automatic transmission and various other parameters to optimize the torque and horsepower curve for each individual application. Chassis Dynamometer tuning allows JET to develop a specific program for each application.
Every vehicle is first tested in a stock configuration to get baseline dynamometer and track times. To do this the vehicle is connected to JET's custom data acquisition system to monitor various sensors. Engine temperature, spark advance and air/fuel ratios, all this data is then recorded and stored away for later comparison.
From there we start to modify the spark advance and fuel curve in 500 rpm increments until we achieve the maximum torque and horsepower at the drive wheels in each rpm and load range, this allows turning under all types of various driving conditions and not just wide open throttle, a decisive advantage to the JET chip!
All the Data is stored on disk and transferred to the JET chip program so thorough track and street testing can be done under "real world driving conditions" to assure the Dyno results prove out on the road in decreased 0-60 mph times and quicker ¼ miles acceleration.

Where does it say all throttle positions? Of course they tune at 500 rpm increments.... but at wide open throttle only. Nothing has changed, they still only performance tune at WOT.

Apparently, they've made changes in the last 6 months to that page since they came out with their new hand-held tuner.
Regardless, your chip tunes at WOT only. Your chip was designed when 87 octane was the minimum requirement for their chips and changing the thermostat was recommended by them. Call them and press them on the matter concerning your era JET chip. That page changes nothing about their older chips used in old trucks like yours. Your $30 JET chip is not going to do the job of the more expensive chips.
I have to laugh at JET's dyno charts as well, they selected the 1995 Mustang as the Ford test.... because that year had such a poor factory tune that simply switching out the computer for another stock computer with a different calibration code gave about 15+ HP. Why can't they show a 2004 F-150?
Go ahead, buy a used chip, I don't care. Buy a used Diablo, SCT or Superchips instead and get better results.
