RE: powerlost in 1st gear only no boost procharger
If the car goes into fail mode won't that show up in the dash or something? (idiot light or throw a code?) Does your handheld tuner show it? I am new to S/C' ing and have much to learn. I dont think that the gear and 6 spd have anything to do with it but I have no realfacts to back it up. Email CrazyAl and ask him....I have not seen him here in a while but do a search for the author and type it just as I have and maybe he can shed some light on the subject.......what tells you that the car is in fail safe mode? FordFanBoy should be able to help too. Have not seenhim much either. Some of the regulars in the Shelby section might be able to help too as they have S/C'd GT500's and such. If the problems ever gets fixed let me know. Do you have photobucket? Set up an acct and post a link to the video after you download it. If you dont have photobucket its free and real easy to download the video from there. Hope it helps

So any improvement?....sounds like belt slippage to me! Since the car is dynoed in fourth gear it probably wont show on the dyno. A boost gauge will tell you if the psi goes way past what the pulley is rated for hence belt slippage. JMO

I don't know your problem, but I wouldn't suspect the gears, makes no sense. Possibly something wrong with the transmission. Clearly the pcm is not allowing WOT for some reason in first gear or else it would make boost.
An aeroforce gauge would be very useful in this situation because it could atleast show the throttle percentage the pcm is reporting. Mine will be here tomorrow!

Thanks for your help Its not the belt that was the first thing i checked. The computer is going to fail mode in first only, no wot? The car worked fine untill the trans and gears went in. Do you think that the 430 is to much for this trans? the car does run better with the 20s on. I do have a boost g and it shows no boost in first,once i shift to second its right on it.First feels like a total stock car I cant explain and just cannot seem to figure it out.I tried to get my camera to film it but can't get it to down load.any help you can give me thanks

Actually if the belt slips the boost will go down then back up.

Well the problem seems to be fixed .It cost me less then 5 dollars. LikeI stated I paid a shop 300.00 dollars to fixed the car, It worked for about5take offs then back to the problem . Said it was the TB so he put his on untill i bought one . I order new one same problem. My buddy has a grand nation with a turbo Hetold me to check all the clamps for the charger and found two that seemed tight but was damaged . Does this make sense? Well its fixed and never been this fast.I'll find out what it does friday night at the track . Thanks for all that tried to help.
