I ordered my JRSC yesterday and will be starting off with the 7psi pulley, DCRH and Injen CAI. I've already downloaded the K-Manager software but there is nothing for that setup.
The closest ones are:
K20A2 Supercharged 5-7 Psi
K20A2 Supercharged 9 Psi
The current JRSC kit I'm getting comes with 550cc Injectors. I plan on getting it professionally dyno tuned to begin with but I don't even know where to start off at. Can anyone give me some insight into the matter.
JRSC + 7psi + 550's; What cal?

JRSC 9 PSI
I have the same setup as the thread starter. DCRH, JRSC.
I am using the cal JRSCH 5-9 PSI Kal. I notice that it runs great in NA mode but when you go into boost, it is extremely rich.
I would start with adjusting fuel from column 11 to 13 first and bring AF ratio down to around 11.7 to 12.3. I noticed that depend on air temperature, the AF ratio will varies between that amount and don't forget to use Conrads air temperature chart.

Are you using the 5-7psi kal or the 9psi kal?crackerjack wrote:I have the same setup as the thread starter. DCRH, JRSC.
