hi has anyone heard of a prova ecu,i have one on my95 wrx,can any one tell me what it might have done to it ?
also what sealant do i use to put new rocker cover gaskets on, it says to put some on the four front points also on the half moon peices at the back ,can anyone give me some pointers?
cheers graham

 

Prova add a chip to the ecu ,most probably mapped for jap hi octane fuel and increased boost.
Have it checked on a rolling road to make sure the fuelling is alright.

 

threebond sealer 1215 get it from any subaru main dealer for about 12 quid and spread it on everythin all the way round.
