Apparently it's important to replace the stock Evo 8 (not IX) fuel pump with the Walbro 255 if increasing the Evo's boost beyond stock levels (18-19 peak psi).

Al from Dynoflash will not sell you a flash if you're implementing an MBC/EBC unless you have one installed.

*Shrug*

Dunno all the tech details but it's being implied it helps prevent small-percentage of massive engine failures ...

Just an FYI as I got raped for questioning it at EvoM since I'd not heard anything about it yet ... rolleyes.gif

Thank you, that is all, back to feasting on V-8s...

It was my understanding that its not necessary over 18-19 psi , however...the reason people recommend it is because eventually you will make it to that level and its cheaper to have it installed and have Al do the flash WITH the fuel pump, rather than having to upgrade your ecu, then upgrade it again when you get the flash....
