Boondocker Tuning Guide

[Sunvang]

Anybody have a, or could write me a quick tuning guide? Sled is tuned ruffly and is running good, but could use some fine tuning. Running the 2013 BD kit with integreated ebc.

Some "issues":
-From idle to WOT the sled hesitates alittle and takes about 1-2 sec before it really gets on the rpms and get going.
-Going from WOT to 0 throttle and back to WOT many times can cause a bog. This happens 1 out of 40 times maybe.

Looks like i need to go down on the RPM adjustments. Dont think i can go that low on the 7600 and 8200, im at 11.5 a/f on WOT and dont want to go higher.
Thanks for the numbers!

Im at 6psi, straight pump gas, 1500-4000ft, 10-76 weights.

lol 11.5, no wonder its boggy. thats way to fat, but i guess thats how your getting away with that level of boost on straight pump gas at such low elevation.

I run 11.7 at WOT and it pulls fine with no bogs. Both my turbo sleds love fuel and have tuned both to 11.7 rest of my throttle is 12.5-13

 

[Sunvang]

So what is a safe WOT a/f ratio? Thought you shouldnt be over 12?

12.5 usually

 

[Sunvang]

Been told thats a little high. But will try.

 

[philsummers21]

I like mine in the high 11s. for WOT

Lean Spot

Do you guys add fuel and try to tune out the lean spot at about 4500 rpms? My BD runs great!! I hate to change anything but I don't like looking at the AF gauge read lean for a second. I have heard the lean spot is on all Polaris sleds (stock) just not sure if I should try to tune it out or not??
Thanks!!
