Hi everyone. I am currently running various mods un-mapped and plan to get a remap very soon. Remapping is new to me as I have only had the car a short while, which is an MY98 Impreza Terzo. I am aware that I will need a ECU upgrade to get the car mapped.


The car spec pre-remap is:


TD05 16g turbo
full Blitz turbo back decat (heat wrapped with DEI Titanium wrap)
upgraded STI top mount intercooler with modified under tray & big scoop
upgraded aluminium radiator and twin fan aluminium shroud
Apexi induction kit with purple MAF
Uprated fuel pump (I think the fuel injectors are standard)


My questions are:


when going for the remap, what information will I need to give the mapper other than that above?


Is there anything within the list above that will require or would benefit from further upgrades prior to mapping?


I am trying to get the car to a respectable point prior to mapping in an attempt at avoiding having to remap the car every time I do an upgrade. Other than the above changes, I only plan to upgrade the suspension set-up and possibly the brakes in the future.


Finally, realistically, what sort of power do you think I would achieve with these mods?

 

I have pretty much the same setup, just got a harvey ported and wrapped exhaust manifold and a harvey trick up pipe to meet with the rest.

I'm rebuilding the same TD05 16G as which is already mounted but going to put 440cc injectors in it, because i'm not wanting them to max out.

The standard 380cc's I believe are good until 290 but I'm hoping to pass the 300 HP barrier.

 

I think I will also swap out the standard exhaust manifold with a new stainless and wrapped one too, if the budget can stretch.

so, if I want to break the 300bhp barrier, I will need to upgrade the fuel injectors?
