well actually a intercooler is not a needed item unless you plan to exceed 8 psi i am told and if you get an aftermarket ball bearing turbo it raises that number higher
now the reason being that you lose a slight amount of boost andf the chargde is cooled only so much so the result is that you boost the turbo up more to get the same psi and as a result the turbo has to woirk harder so unless you go aboce 8 psi then start with the exaust then the intake then get a boost controller and go to 8 psi
if still not enough power get the intercooler and go to 10 i dontr recomend going past 10 without an intercooler at any time unless yopu have really high octane then you can hit 12 usually with little or no problems
good luck and is it electronic controlled suspention
and does it work if it is???
mine is and i love it just dont hit too many bumps at 110 and try and slow down aty the same time in firm lol and also dont try and switch the position iof the knob whil;e hiting bumpos it usually sets mine into fail safe mode (all lights blinking on the knob)
