How much power am I giving up by using a tube/fin IC?

You wont give up any power. As long as it is big enough, either design is fine. Bar plate gives less pressure drop but isnt as efficient. Tube-fin doesnt flow as much, but what it does flow gets cooled a lot better.
Bar plate is slightly sturdier but also lots more expensive, since most bar-plates are custom aftermarket jobs and most of the tube fin intercoolers are OEM ones that have been converted to project use. I'm using a tube-fin mk3 supra intercooler that has served me very well for years now.
That reminds me of another thing. Take things other car owners say with a grain of salt. An intercooler that "sucks" might have been fitted to a much larger engine or have very restrictive stock tubing around it. The MK3 intercooler is supposedly a turd, but it is a huge (for a miata) unit with nice end tanks (I relocated mine), perfectly sized for a T3/T04 sized turbo (2" inlet/outlet) and you can easily make much more direct pipes than the MK3 supra comes with stock (looks like spaghetti under the hood).
Also, beware of small bar-plate jobs that have crappy end-tanks and are sized for 180 whp D series honda turbos. Lol ebay.
This is back from when I painted it. Yeah, engine enamel > powdercoat.

C or F?
I typically see 10C (give or take) above ambient just driving around. It goes up another 10C or so in boost but drops back down quickly. I havent datalogged in a long long time. Typically in low 90s ambient I will be around 40C or so just puttering around. In boost I can get up to mid-high 40s C.
Basically the car is fast below 90F weather, sluggish above. Below 40F, the car is very fast but I have to redo the EBC settings to avoid overboosting.
