uh, i wouldn't run the nitrous at the redline. when you bounce off of the redline, that's your fuel cut, where you ecu cuts fuel to the engine. so you're running lean at that point, and i wouldn't want nitrous in there when that's happening. bv1, you run to 6700 rpm? i thought tibs had a 6500 rpm fuel cut (at least mine does).

 

The redline on the beta should be 6500. The fuel cut should be 6750.

The MSD Window switch is the best way to kill Nitrous before you hit the rev limiter. Holly also has a "NOS" brand window switch out now as well.

 

you're right about that random (not like i'm gonna argue with you any ways). i wasn't thinking, but i forgot that my tach is off by like 200rpms (thank you s-afc).

 

Hey real quick but this is my thought....Does the Rev limiter also affect top speed in certan gears....Like the last gear of my auto...Because there is still power left but it slows down.....I mean the acceleration slowns when im in O/D and arund 110-115+ around 4,650+ RPMs...Is this also part of the ECU programed...
