Results are in.. JERRY,,, RR IC !!
Well I am gonna just be honest up front. I didn't see a HUGE difference in the RR IC.. I even felt I lost Bottom end grunt..
What I noticed was the ski pulled to 8100rpm's faster than normal and it was able to put me a 70mph with a Full tank of fuel. But a average of 69.9.
I was about 68.5mph before on a full tank of gas..
Stock prop
Ride plate filled
Power pipe
fresh air.
I checked the boost gauge allot and it was just not very accurate. It was reading just above 5lbs of boost and wouldn't read any boost pressure ridding around at about 5500 rpm's..I really couldn't tell you if I had a boost leak as this gauge looks to be in the neg before I even start the ski..It is not in the middle of the square starting box but in the neg.. So I think I was running in the 7.5 range, but not sure..Gonna get a more accurate gauge.
Anybody any thoughts???
Gonna get thoughts first before I say I am glad I didn't pay full price for this IC...

Austin, what gauge do you have, and where is it mounted?...PR...
also, when your are cruising or at steady no load speeds you will actually see a vacuum reading and not boost pressure, you should see boost when you accelerate...PR...

I'd say check your IC blockoff. Seal it with some Ultra Blue or something. I was loosing lots of boost there.
But is the RR IC supposed to do much without the RR ECU?
