i have a M2 intake, megan racing intercooler with Greddy 3 piece piping, apexi GT exhaust, HKS downpipe, HKS SSQV BOV

what should i get next

wastegate?
ignition?
fuel system?
engine managment?

 

do you have any problems boost spike or creep? do u have a wideband to see if you are running lean?

basically what im saying is we need more details.

 

Power FC. Leave the stock main cat on for now. Does your 'el cheapo' intercooler have a duct?

Also, don't forget about the maintenance.....when was the last time this stuff was done:
Spark plugs and wires?
fuel filter?
tranny fluid?
diff fluid?
coolant?

 

radiator-

 

Get a PFC
more fuel won't do anything unless you have a way to control it

what would you need a wastegate for? are you single?

and ignition is much further down the road

an aluminum radiator is not a bad idea for reliability reasons

 

1. ECU
2.Maintenance
3. Rad.
4. Maintenance
5. Fuel

 

would it be a good idea to forget the megan racing intercooler....and get a new high performance one

is it worth the money?

 

Power FC first and foremost.

 

my vote goes for a power fc
