Hi Joeleo87
Many of my friends have used Hypergear products in the past including me.
A friend of mine just made 238kws on 18psi on a rb20 with a much, much better power curve then me, only thing is his got a power fc and full exhaust system where as i have a hks 2535 with stock dump/front and a emange blue. so tuneability wise its not the best (my car).
Point being, people buy cheaper (price wise) turbos because they are on a budget... and if you are on a tight budget you cant buy support mods (tune, ecu, fuel pump, afm, injectors ect ect) good enough to get the max potential out of the turbo.
thats why some people will say a product is crap while others are in love with it.... it all comes down to the build up.
get the hypergear, get a remap or a pfc and you will be loving life
