finally installed it today,performance first,decent throttle responce and spool up even with the phat shat 66,however if i jump on it while pulling out of the drive and let off the go pedal by say 40 the motor stays loaded up with fuel and you cant hardly hold the truck back with the brakes,next thing you know your going 50-55mph.its just not safe to drive,i called superchip and asked a tech guy about how much pressure they use and he wouldnt tell me,i feel its to much pressure as i get the same thing when i crank up my ts power play to high.the red line is definatley raised i saw about 3850 on the tach,i tried the tow asetting and i didnt get the let of surge but didnt get the rpms either,mine is boxed back up and goes backto superchip tommorrow..it is important to add i that my truck has bigger injects and loads up with fuel much more than it ever did with stock sticks

 

Interesting, thanks for the info. are you sending it back for good or are they sending u a new one (which they are pretty good at doing that) Would like to know how it does when the new one gets back. get any smoke at all?

 

has anyone else tried the tuner???

 

How about tranny shift points??

 

i would be interested to hear if it happens with engines that have not had injectors upgraded and is purely stock other than air intake and maybe exhaust.... if I read right that you had larger injectors.

thanks for update...

 

yes i do have larger imjects and they do not react well to fuel pressure,the shifts are a good bit faster thannormal and with the raised rpms there is no defuel between shifts.there is good blast of smoke then a decent haze up to about 100 mph'''i am sending back for good not another one,i am sure it has to much fuel pressure to work safely as a driver for my needs

 

would be interested to hear what they tell you and explain as the issue if you dont mind sharing when the dust settles...

 

i asked they wouldnt give me any fuel pressure info,confirmed or denied,just wanted to to run it for few 100 miles to see if it straightens out ,but not worth the risks

 

King D, Did it remove or raise the speed limiter?

 

i was told 130 didnt try it up that high but deinatly rised somewhat
