dont bother..
My theory here is that intercoolers are great if your car is going to be reving its titties off constantly, your turbo will heat up trying to fit more air through it than it can handle in turn making your intake charge hot.
Now im assuming this is a street car not a race car, if put my arm out the window now driving along its a bout 25 outside the sir feels cool to touch, my car is sitting on about 3000rpm, maybe it will get up to 5 tops so my turbo is barely heating up so cooling the air isnt going to prove much and an intercooler is only going to be good for hektik points which doesnt actually make your car faster.
Now, are you getting a remap or retune,,a remap will cost about 500 and completely remap your ecu, a retune will cost about 100 and just fix some key points
if you are actually getting a remap spend about 800 on one of hypergears hiflows and you will notice a huge difference in power and be able to crank your boost up considrrably. In doing this you will have alot more power so you wont have the need to thrash its tits off to get anywhere .. Then monitor your intake tempss to see if they are too hot, chances are in everday driving they will be fine. If they are not then get an intercooler .
If you are just getting a retune...dont bother. My car was making 185kw with a stock cooler and never had any problems with intake temps...
If you are going to be racing the car constantly then get one..
