    First make sure your ceramic washers have been replaced first before you got out again. Seriously. People will say replace valves and fly wheel bolts. Sure some have had failures but more of us haven't. Take everything with a grain of salt on any forum. I will say this this bolt on mods are the cheapest, easiest, and still maintain reliability. I'd start with a intake grate and a air intake. This again is a debate on where you ride and what style of riding you do. From here you can bigger charger and intercooler. The water boxes, tunes, injectors, opas deletes, rear bucket deletes, reduction nozzles, etc. start with a intake grate and get the engine some air.

    Hands down best single mod you can do to any stock RXP would be a supercharger impeller. I ran a Riva Gen 2 impeller on my bone stock 09 RXP the first year i had it and i absolutely loved it. Definitely the most noticeable power improvement/ bang for your buck single mod.

    You could always do little things like an air intake/intake grate or other small bolt ons but at the end of the day increasing your boost is going to give you the most noticeable improvement.

    Riva gen 2 is good with stock injectors. Super solid setup and very reliable

    He may be better off finding a solid used x charger depending on prices

    Im skeptical on how solid that set up really is on a 215. Has anyone documented their AFRs? I know they say you can slap it on and not worry about it if your on stock Intercooler but id really like so see what numbers its running.

    Im maxin out injectors like theres no tomorrow. Keep runnin into the dreaded 100% duty cycle like its a damn wall or something. Ive tried 48s, and 2 different sets of 50s. I got some Deka 80s on there way now. Hopefully thatll help if not im gonna have to run some sort of voltage clamp on my map sensor to trick it into thinkin im runnin less boost than i really am that way it wont hit 100%.

    other than that its running in complete beast mode and im seeing 76.6-77.5 mph consistently in the chop.
