Need advice from all use serious modifiers

(Where as I just play at it when the spare cash comes along from my friendly bookies lol)
Recently added a new Exhaust for the performance gain and the looks.
(Just as well I wasn’t looking for a loud exhaust cos it’s on the quiet side

Contacted the company who done my remap (Celtic Tuning) and listed
the various modifications I have had done since the remap and asked do
they think I should have another remap to obtain the max out off the modifications.
To my shock they said no the existing software should be fine, but reading on various
posts most off use guys have a second remap (now I am confused help!!!!)
My mods are - Remap, Forge bypass valve & Intercooler, BMC CDA Induction Kit & Milltek TBE
