I want to upgrade my turbo to an HTA3076R, but im not sure what supporting mods i should have before i do it. my car is pretty modified as it is. do i have to buy a whole new standalone ECU and run speed density setup? or are people having good luck with the stock MAF and a tune?

 

you need to search

to give you an idea (I'll assume by "pretty modified" that you have bolt ons)

injectors

aside from those you might need a different licp and various water/oil feed/return line parts

stock ecu and a tune will be just fine

a standalone will net more power
