Most kits are pre-jetted rich for safety, and will produce more than rated power if leaned out slightly (like 5%).
NEVER use it under 3,000 RPM.
It will severely beat up an automatic transmission, since (unlike factory turbo AT) it doesn't turn down the power via spark retard during the shift. You can add this feature with some expensive controllers (MSD) but remember this is a PB on your factory ECM.

This is absolutely the most power for the money, but yes it will destroy the engine if you make a mistake ("what happens if I increase the jet size?")

GOOGLE it if you are confused (i forgot how to explain it. but here goes.

Mods: JOE Z Exhaust, K & N filter, Homemade intake, Deleted the crankcase breathers, heat wrapped air box.
357.2 whp Dyno dynamics read out
425 whp Dyno jet
401 whp Mustang Dyno


Same mods With 50 shot of nitrous from Nitrous Express kit
389.6 whp Dyno Dynamics read out
463 whp Dyno Jet
437 whp Mustang dyno

Same mods with 100 shot of nitrous from Nitrous Express kit (didnt have the right fuel jet for this shot afr was very rich)
461.7 whp Dyno Dynamics read out
550 whp Dyno Jet
519 whp Mustang Dyno

Same mods with 115 shot of nitrous Nitrous Express kit (kept same fuel jet as above)
494.8 whp Dyno Dynamics read out
589 whp Dyno Jet
556 whp Mustang dyno

The shop i visited would multiply 1.15 to their number for an industry average which my final number would
read 572 whp. So in all i gained 140 whp difference on only a 115 shot nitrous which leave me a little perplexed but. the AFR is happy and i managed to beat up on a newer GSXR i assume was a 600c. on the highway with a 2nd gear roll and 3 gear roll after 2 gears he could not pass me i kept a car length lead on him and if you know anything about bikes their upper gears are usual weaker and i would have pulled an even larger gap. I need to run some cars now, to compare my car to the two Nitrous RCFs in Florida.
