Ok, i remove my 3.8, built my own 4.1. Now the 4.1 is amazing. Anyway, im running the same chip for my 3.8, for a 61 turbo(TT). Now i have a 6776 turbo. The car needed like 12% more fuel at WOT. Then i add a FMIC today, and had to add 19% more fuel, and the car go's lean on and off, maybe when i lift off the gas a little. So do i need to get another chip cut, or add a dual spray for alky? Also i have hardly any tension on the rod, and the boost is 20+psi, i had to back off 8turns on the rod, just to get the boost down, after i changed the intercooler.
Need info on next step?
