I have an 05 f150 with and afe intake and full magnaflow exhaust. I bought the vehicle used. It previously had a superchip program already installed. I just purchased an Edge CS and had the computer flashed and and installed the new programmer. Now I'm really lacking on my bottom end and throttle response. Does anyone else have the superchip installed? Or is there anyway I can greatly improve my throttle response on my CS? Please Help

Sincerely,
Björk

 

With regards to “Chips” and “Tuners”, years ago it was the best that most could do to enhance the ignition timing, fuel curve, transmission shift points, etc. It was (and still is) very important that a person verifies that the “Tuner” is ASE certified in both ECM and Transmission programming and IMHO be have current certification by the OEM whose vehicle you want to modify. There are plenty of persons who advertise their programs to be the best and even offer custom tunes, but in all reality, very few actually have credentials in these areas- but that’s not to say that some of these “geniuses” haven’t really caused damage to a few vehicles- just jump over to flatratetech.com and read just some of the comments from the MSE techs!. Perhaps what is equally important is the parameters that can be adjusted are set by the oem vehicle software…so there is really no “magic” in what they are doing anyway. Now about this new marketing hype that if you have a CAI you need a custom program………….hogwash!!!!!! The oem software system is designed to adjust the fuel mixture up to 10%.......that’s more than enough to handle fuel mixture adjustments up to 7,000 foot elevation change! (for high elevations 8,000+ there are oem software programs for those specific applications) The 5.4 V8 for example if close to stock can only suck in a maximum of 480 cfm and a flat panel filter will flow 500 cfm, there is simply no way any CAI on a relatively stock engine can increase the air flow enough to exceed the ECM’s ability to adjust and maintain the correct fuel mixture. The only reason for the “custom” program to support the CAI is because the design is poor resulting in false readings from the air intake sensors, etc….period!

IMHO, if you live near any major city there are excellent tuning specialist with dynos who for the same price (if not less) will tune your vehicle taking into consideration your specific needs including environmental conditions, for your specific vehicle. IMHO, the best bang for the buck!
Now to correct just the throttle response (only)...
Throttle Position Sensor- Ford Specific

Volt Meter Procedure to inspect and adjust:

• Turn ignition to “On Position” with engine not running
• Set multi-meter to “VDC” position
• Connect negative meter probe to any ground
• Connect positive meter probe to the middle wire on TPS
• Read meter: Target range is .995-.999
• Do not adjust above .999 or idle problems will occur
• Adjust TPS by loosing screws on sensor enough to get some play while watching meter.
• If unable to adjust above .956, remove sensor, slightly enlarge mounting holes to obtain more “Play”
• Once setting is obtained, tighten TPS screws & watch meter reading.
• Move throttle to wide open position twice & recheck meter readings.
