Maybe a turbo problem?

Re: can't launch
you wont create much boost at all at idle because of the way a turbo works. pull your plugs and see how they look, do you have a wideband? since you said its blowin coal check your air fuel ratios...sounds like youre too rich. just try taking 1 maybe 2 % out of that section of your map and see if it gets better.

increasing how much air the turbo flows at idle is both inpossible(without a new turbo) and unnessecary you need to take fuel OUT not add more. put your computer back on with a WB and stop dickin around and tune that bastard!

Re: can't launch
Done, i went to the yunkyard and i pick a volvo turbo .42 .48 for $25, so i change the thunderbird .48 .60 for this new volvo .42 .48 and now the problem gone, the car doesnt bogs anymore and runs like a bitch, but i use a FMU at 6 psi only.
So the problem was the turbo itself.
Now i have a question.... i have my 450cc and chipped ecu with a bin at 11 psi for the old .48 .60 turbo, i know i need to retune, but what happen if i still use the same bin at 8 psi?, i will be running rich or lean maybe?
