[E86-3.0si]

Hi,

I just saw Celtic Tuning online for my 3.0si. The performance increase was quite impression in my option from 261hp to 279hp from a NA engine. Will this effect reliability? What are your thoughts?

I got a email quote and it costs £295 for the remap.

(They have a mistake on '35si')

Thanks
