No, It's only the one pcm doing it. I bought the car with the tune and he did it himself so I have no clue what has been done as far as that is concerned. The mods as far as I know is

Spectre cone filter
thrasher intake box
ported exhaust manifold
3 inch exhaust all the way back
exhaust has been heat wrapped in engine bay
magnaflow high flow cat
magnaflow mufflers (not sure what type)
U bend delete
180 t-stat
colder plugs
Taylor spiro pro 8mm wires
And thats all it has for engine mods anyway
