Hey guys,

Running an 850T with ibex 20hp tune,

When I crack the throttle out of the gate I see 7600rpm and then it creeps its way up to 7900-8000.

What do I need to do to correct this? It’s like the exact opposite of RPM fade WOT

I think it was too much tip weight. I have slp adjustable weights, I pulled a bit out of the tip, added a 1mm larger pivot bolt spacer and put the stock primary spring back in 160-350 i think? And pulled out the Gen 5 150-250 spring.

Man what a difference…. The thing straight up pulls now and feels how a factory turbo should. Hits 8000 drops to 7900 and holds. 7900 feels 10 times better then 7700 to me on this sled..

Clutching problem.



Or it need to be reflashed heard of similar issues like this.
G5 spring is not a 150/250.

got a 100-250 in mine w/ clutch kit. the factory engagement is needlessly high and stock clutching still leaves something to be desired.
