what is can say is this thing is really lousy crab product!!!!
when u go to install they just put something like a small pcs twisting alloy
in to your air filter raim.....u can't feel anything as well,
coz my friend try it b4...crab crab crab!!!!
u got 2 choice.if u want a normal pick up performance for N/A mod with low budget....
1.change a better air filter i means branded one...like k&n drop in type
2.setup your piping change extractor add on bullet and cut off the catelic covertor
use back your original 1.5inch piping...and change the Pro1 Racing muffler...don't use those direct out one ...lousy noisy and crab!!! like lori
3.tune up your patrol setup,like that would get more powerfull(but makan patro)
like this is the cheapest setup
if u really wanna go for turbo just keep money get a half cut...and convert
but auto car if u really wanna get those performance like super improve abit hard eh..
it will automatic change your gear less 6k rpm..like that not enought or else u need to
setup your ECU to default...means control the change gear to 6.5k rpm...only got more power
