I installed a new PTE 5831 turbo, 60lb injectors and a Turbo Tweak chip 5.7 chip for my 87 Gn. At WOT my wideband is reading high 14's to mid 15's. From past tuning on turbo cars I was thinking 11-12's wideband at WOT should be better. Should I order a new chip or crank the fuel pressure up? I was going to email Turbo Tweak but cant find any contact info. Any help would be great.
Thanks
 
Most likey Eric will have to reburn that chip to your new turbo , if the chip is less than a year old he may update it for free . Info should be on his web page .
 
If the chip was made for that combo (with the 5831) and it's that lean, then I would check into the fuel system, etc, or even a bad wideband sensor.
If the chip was made for a different combo, then it may need to be reprogrammed.

email is eric@turbotweak.com

Eric
