2006 Mustang Gt, Predator U7140, V.9r04 Univ_Rev

Hi I am going to run a 100 wet shot of nitrous I am using the K&N 91 octane tune right now but I use the 93 octane firm shift when I race at the track. Will that be ok? It says to retard timing 2 deg. is that in the global spark? Thanks for your ...

Problem solved removed and cleaned throttle body had dirt around the butterfly's choking it out, no problem with start and now idles where i program it.....

why would the rpm change in the modify tune not take? how can I remedy this?

ok I got the original backup working ok car starts and idles, but I have 3.73 gears and if I modify the tune I get the wrench. What could be the problem. Car will not start and idle any longer with the canned tunes. the only change I made was autolite sparkplugs?

well it was short lived, changed back to 87 tune still has start stall issue, went back to stock and get limp mode, tried several tunes all have start stall issue, I had changed the plugs to autolites, and then had start stall issue My guess is I need to look for a vacuum leak.

went back to original backup and seems to have corrected itself, will try going back to a different tune in a few days, thanks. Mike

I drove with a friend today that has alot of knowledge he said that it could be the start of the voltage regulator going out but he was stumped also. We drove down the road set the cruise at about 45 then I hit the high beams and the engine stuttered I did this several times weird? As for the stock ...

06 GT U7140 running 93 octane firm shift, I was heading home from Sebring last nite when I hit my high beams and felt a bump in the throttle I would turn them off and feel the bump again also with the turn signals, now why would a power draw affect the running of the car? I did this off and on for a ...

I believe that worked, Another question, should the check engine light come on with the hego turned off the only code i have is the catalyst bank 1 & 2?

I'll give that a try, Thanks.
