Did some searching but couldn't find a definite answers.

#1 If I want to run 12 psi on an M2 Ecu should I upgrade the fuel pump from stock or is it safe?

#2 When do I really have to upgrade the wastegate and is a tail 38 good enough or too big for stock twins?

#3 Whats the quietest midpipe for the seven over stock?

I don't want these mod's open up pandora's box, will the M2 ecu and mid-pipe F up my cars reliability?

Mod's I have as of now ~

Mods planned ~
M2 Ecu 12 psi (programmed for all basic mods)
Rx7store mid-pipe ~ From what I heard it's the quietest
Walboro 255
Tial 38mm wastegate (If needed)
Custom 24x18 V-mount Intercooler ~ I know this will drop temps dramatically but will it create more lag and is this overkill for the stock twins merely boosting only 2 psi over?


The M2 Ecu is for 12 psi so I'm assuming I can use the EBS to keep it steady at 12psi or will it creep unless I upgrade the wastegate.

 

Generally, its fine. However, tests have shown the stock pump falling off as the boost increases. It wouldn't be a bad idea to either do the fuel pump wiring modification or use a better fuel pump for the increased boost setting.

The wastegate is internal on the stock twin turbo manifold. There is no changing it out.

Any resonated midpipe will do. A lot of people have had good success buying a standard midpipe and welding in Borla mufflers. However, that way is more expensive but IMO Borla has better products than Magnaflow.

 

Thanks, Works out good because I have a straight pipe just need to pick up a borla resonator.
