Eprom chips plug in to replace the orignial chip (had one on my old 996 to "adjust" for open cans and air restricters removed)
Think the Tuoldo can be chipped, the Tuono is a case of map 2 (dealer job) .... n a power commander if you want more than that.... (PC plugs in and adjusts the original / existing map - ie doesnt replace - so you can remove it and all goes back to "original")
am sure someone will be along to correct this if im talking crap as usual !
Yep,^^what he said.^^
The 2nd Gen Tuono uses a completely different ECU to the Gen1.Any tuning has to be done with the dealers Axone meter or a Power Commander.
