I have had the revs raised.. STOCK Inj.

Inj are at 100% cycle rate at 6900 revs.
Went to JCW inj, and they were at 100% cycle rate at 6900 revs also.

OEM MAP at this time.

Just thought you would like some dangerous opinion..lol

SOOOo... I would say the JCW inj and Tune will carry a 6900-7K engine. ( ?? )

Just me.............................

i think ull be fine...ive been running the JCW 380s now for 70+k miles without an issue

here are my mods
15% pulley
Alta intake
RMW torque cam
RMW shorty header
magnaflow exhaust
brisk plugs
RMW tune
+ a whole bunch of ancilliary parts here and there

as long as you get the sucker tuned right you should be fine...though i cant speak for the condition of your engine but i know that in my case the 380s were just fine and ive been running all over hells half acre with my mini and it hasnt missed a beat

 

Also, yes.

As Thumper was pointing out as long as your on the stock rev limiter you can do most mod's and they will "work" simply because of not trying to go over 100% duty cycle for extended periods of time.

The only real difference is not being able to take full advantage of your parts, but the ECU will adapt enough for it to be safe.
