The usual bolt on mods like most have like full turbo back (decat) exhaust, induction kit, manifold, bluefin, uprated chargecooler, better plugs, leads, etc, etc, etc to get around 300
The bluefin i used back then was just the basic Bluefin map designed for FRS (standard/modded) & it ran fine
For the mods you have there are many people on the RSOC running similar mods with Bluefin/Dreamscience so shouldnt have any worries there
You may also want to consider replacing the actuator so the car holds boost better as well as putting bluefin/dreamscience on the car
Bluefin also supply maps designed to run on cars whereby people have fitted a hybrid gt25 turbo or gt28 turbos where things like fuelling, ignition are adjusted over standard
AFAIK Dreamscience does similar with its higher spec handsets in the form of maps like "Race" or "Race+" & quite a few people use them on cars ranging from standard to modded as well
Of course Bluefin (Superchips) & some Dreamscience dealers can also offer "live map" services tailored to mods on your car if you desired that
Other than that the other usual chips on the market for the FRS are the Dastek Unichip & Collins Powerchip options although these are more ideal if you want to have a custom map setup to the mods already on the car
The next stage on from there is standalone ecu with proper live map but that is basically 380+bhp territory whereby you need to be able to have access to pretty much 100% of the cars engine/ecu setup - thats what i'm on now but obviously only due to the cars power/mods/etc
If you get a chance have a look/ask on the FRS section of the RSOC forum as there are quite a few threads on there with the usual good & bad points of most of the ecu options available & also a few threads relevant to replacing the actuator as well
