I have just swapped out a T04E with a 1.15 T4 rear and a 57mm inducer for a T04Z with the same 1.15 rear T4 housing but the usual 69mm inducer.

I have an innovate wideband with a XD16 and AFRs look good with the old T04E but maybe a bit rich (reading 11s at idle).

Now that I am going to the T04Z i need to get the boost maps set up for some road tuning. If I add about 25% to each cell in the positive boost screen would that be a safe basis for tuning?

Other details which might help...
6 x 1000CC ID injectors
Turbosmart 2000FPR
Two Aeromotive in tank, stealth pumps.
Previously running fine - used to daily drive prior to turbo upgrade.

It takes trial and error! Up it up more fuel and watch the wideband and use the data logger to see what's its asking for? The fuel setup you have sounds good. Its running pretty rich in idle I usually like it @ 13-14.1 in idle. But see what it does under boost. Also to help I usually save the old map just in case you have to come back to the roots and try something different.. That's my input ////
