car came with a tune but im restoring the car and adding the full fuel system, turbo and valve springs so im looking for some help getting it started with the new parts, thank you!

seeing as you're not changing the injectors it will still start and run on the current map - so after that you can start dialling it in to suit the new turbo.

the ID1050x are new to the build, including rails, -6 AN lines and the FPR

i also left out that it now has billet tgv deletes but had modded tgvs before
lightweight flywheel and crank pulley

assuming your on a MAF tune at the moment if the intake/maf tube hasn't changed then use your current tune to get your injectors dialled in then you can switch to speed density and begin tuning it properly. Even a base map from a similar car will still need you to pass through all the cells in the VE table to make adjustments so it won't save you as much time as you think.
