Forget a hand-me-down map. If you want to get serious with the horsepower you'll need the following...
Full Exhaust: you got it
PCV: you got that too
Aftermarket Filter: MWR, BMC, or a Sprint air filter ($80-$130)
ECU Flash: $400
Dyno Tune: $400
Dynojet Autotune: $230 (optional)
Est. Total: $2,000
Stock Dyno Power: 175HP
Est. w/ Custom Map: 197HP
2000/22 = $90 per HP
Although: if you just want something to get you by, I would use the 2Bros map over the Graves. The PCV site is unforunately very limited with Gen5 maps atm... You might want to just contact the Racefit manufacturers and see how generous they are.
Another option: Forget the PCV altogether and just get a flash. I would go with Brocks or Don Guhl and just let them know what your mods are, and they'll be able to get your ECU on track. You'll get exceedingly more HP, top speed, a higher rev limiter, etc. (all things you won't get with a PCV). Then return the PCV without opening it!
When in doubt... send it!
