JRSC Race Kit producing only 5 psi.
For a year now i have had jrsc street version on my car. Recently i decided to upgrade and today i finally installed everything.
Changes i have made:
Changed 4.4" to 4" pulley with 62.2 inch gaterback belt.
Replaced ngk spark plugs with ngk (iridium) spark plugs, but a step colder.
Replaced stock injectors with rsx type s 310 cc injectors.
Still with powercard.
Previously the charger was producing 4 to 4.5 psi, as seen on the boost gauge. (Btw had a gates belt on there that was missing chunks of ribs, only after 10K miles)
Now the boost gauge is only showing 5-5.2 (as far as i can tell) at 6.5K rpms
Have tightened the belt as i thought this may have been the problem.
Also i feel that between 5.5K and 6.5K rpms the rpms are not moving up steady, almost feeling as if it is holding back.
Not sure what the problem is, maybe some off you help me out with an educated opinion.
Now this is the cheap way out for not having kpro and tuning, so no need to comment on that.
