Waste gate actuator help.

[Vectorboost]

Recently picked up a 2010 nytro mtx with a push turbo . Going to be running at low elevation 1000-2000 ft... i have lengthened waste gate rod and have boost controller one click from off and making 6 pounds of boost. do i need to get a different actuator to run low boost with controller open. Also having a hard time getting A/f down on wot.. Was at 11.9 but keeps going back to 12.4-12.5 on hard pulls . Dont know if it because of clutch weights are too light hitting 9300 or if my gearing is just too low cause rpm increase. any hep wuld be great

Higher PRMs will cause the AF to pop up. I would get that down to 8900 and see if the AFRs can stay down at 12 to 12.2 tops at WOT at 6 lbs

thanks Mr.Sled . stock 18/40 gearing. I know that is way to low at elevation. what would you recommend for low elevation and boost. also thinking of cutting track down to 1.75 for track life. thoughts.

Off trail more then on trail or mix of 50/50?

If on & off trail 20/40 gearing, if mostly trail and you cut the track down 22/40.

Get your RPM down and see where your AFR is then.

id say mix probably more on trail than off

I would cut the track down and gear up and watch AFR. XTX Gearing 21/39 would be a good place as well or maybe easier to go with what Allen said.

will stock chain fit at 22 top gear
