probablly not, I think he means NPI and untuned he was at 180 rwhp and PI swapped and tuned he was at 265.

^yup... The only difference in mods was a O/R H pipe, 75mm Mac Tb/C&L Plenum, Full 99 PI engine and a SCT dyno tune. Then after that I went s/c'd. Now I'm making 436rwhp. Soon to be making high 500's...


Baby step... Baby Steps.
