i have pfc,cb,dp,and pettit intake if i were to install my large m2 stock mount ic would i have to do any tuning? would it make me run any leaner?

 

It will make you run leaner than you were before. But if you are already running rich, that won't necessarily result in running dangerously lean.

that is kinda what i figured, I did a search on the forum and got no result so thanks.

also, if i increase the volume in the intake piping by adding a larger intercooler will i have to turn up my boost to compensate and still run stock boost?

 

No, quite the opposite. Installing a larger IC will INCREASE your boost levels over what you are running with the stock IC. You can expect a 1-2 psi increase. This is one of the best reasons to upgrade from the stock IC, IMO.

 

Your turbos will still be able to generate stock boost levels without a problem. Intake volume's biggest effect is on lag, because your turbos have to pressurize more area in order to build up a certain level of boost. Only if the IC suffers excessive pressure drop (of which the M2/ASP ICs do not) will you have problems building boost, and even then, the turbos will do it, they'll just work harder.

 

i have to hand it to you guys, you know your stuff thanks for the info.
