hurricanes is good but i copped the shits last time when i got the 500g steak and it looked like it was 250g + gave me like 5 fries, that and i think its more $$ than RnR's
220 and 240kw in an rb20 is a big difference.
you either stay below 220 or get a turbo that will make 240 easy
only thing in common between the numbers is that you will need all supporting mods to make the power safely
think about it..
chip $250-300
each dyno tune about $300, next time u do a mod you got to put it back on the dyno, thats another $300
i learnt this lesson the hard way.
get a PFC or Emanage
