Electronic boost controller with ESL chip...
Now i believe Andy has the boost set on these chips (or the one i have at 1.2 bar) Now im gonna be doing away with the 3 port solenoid to make way fot the controller. Is this wise or should i just sell it and keep the standard solenoid to control my boost

if it's mapped to 1.1/1.2 bar on standard ECU control and it's working i.e there are no solenoid or boost control issues, then keep it.
You will gain very little from fitting the aftermarket boost controller and infact remove the limp home safety ability of the standard ECU.

it would only save fuel if you were gunning it and using full boost and that full boost is lower etc.. but if you are gunning it you are unlikely to be thinking of economy.
In answer to the original question.. you would do best to speak with Andy but part of the beauty of the chip is you retain the original ecu features and functions as mentioned the boost cut etc.. however depending on what boost controller you have you could improve spool and boost response but need to be careful you keep things safe.. ideally check it with detcans, wideband etc. But aiming for the same boost will gain you very little.. although I sound biased you would do better to fit the boost controller and then have it mapped for more boost etc.. depending on the mods already on the car that might get expensive or just be the price of the remap.

if you want to save fuel you have a boost controller under your right foot

Agreed......
what is it with the dual boost thing and people thinking it saves fuel.
I've read it countless times especially with the later cars that can switch to another map with the rear screen demist switch.
All these cars run or at least try to achieve 14.7:1 AFR during cruise and idle...therefore if you want to be economical keep it below approx 3,000rpm and 0psi of boost.
It has nothing to do with how much boost it's running, as Simon says (Ooh, havn't played that for a while) unless your are booting it...in that case you will always want it on the high setting.

Yes.. however you might want to speak with Andy about possibly part exchanging your board for a new mappable one and then getting one of us to map it for you.. or sell the ESL chip and then get one of use to supply and map an ESL board. This works out cheaper than Apexi..

Agreed, I had the same thing many years ago on my Series 1 RS Turbo switching bewtween 150 & 180BHP.
But you were talking about economy/fuel consumption.

and maybe less wear on the turbo if your running around on a lower boost?
I've always had adjustable boost i like it.

Agree that two boost setting has a use but the mpg argument seems to be used to imply it will use less fuel cruising about off boost on the lower setting.. which obviously it won't.
