Can the JB4 produce more than 100hp when used with other components?

For example on a 206kw e888 engine with the is38 what would increase over the standard engine?

Are there any example of the additional hp each modification makes?

That is with hardware mods. On 98Ron fuel we typically see around 55-60kw extra.
