on a prodrive ecu what mods could be done without changing ecu/ remap.

atm ive got a cat back exhaust and air filter.

 

Depends what year.
Classics you can decat fully, add fuel pump, induction like you have. Its only really more advance fuelling mods, pressure/injectors and turbo change that would need a remap.

 

You cant change anything really, if you go for a full decat you will put the boost up and this could cause det (have seen this on a PPP'd classic) so really your stuffed tbh.
Options open to you are get a spare ecu and sell the ppp one, or just have the ppp one remapped.

Forgot to mention you can cap the boost with an mbc once it creeps up after decat. Classic PPP has 1.2 bar instead of the standard, .8 I think.
