Yes there are, have a search for BPU and that wil explain whats needed when upping your boost. e.g. spark plugs, decat, exhaust, restrictor ring and FCD.

I think it may be possible to strap one of there on and up your boost without doing anything else, not sure if its safe though

Newbie question here - but are there other things you should upgrade/add or adjust when adding a BC?

 

Just interested as its a MOD i might add in the near future to my completely stock jspec.

 

Have a read of THIS POST also do a search for BPU and you will find a lot of useful advice. You can increase the boost on a J-spc Supra without the need for a boost controller by removing both cats and fitting an after market exhaust.

I would recommend the Blitz SBC-ID and the Powermeter together as you can set boost maps based on speed. If you want to avoid overboosting on most boost controllers you have to set it up for the max boost you want to run which will occur when you are flat out in 4th or 5th. With the SBC-ID and Powermeter you can set the boost settings based on your speed, so you can allow the settings to be higher at low speeds (which means low load on teh engine) and have different settings for high speeds (which is where the highest load will be). It then means you can hit 1.4bar in 2nd, 3rd, 4th and 5th without overboosting.

there u go.

 

I used to have a Blitz Dual SBC as well, super reliable and used to hold boost really well, until unfortunately for whatever reason, the solenoid failed (im told thats very rare).....now ive got the apexi avc-r and this for whatever reason hasnt been performing right since day one.
