We have been running into cases of this lately. Customers complaining of cases of mysterious problems with their sleds. Bad bogs, random hiccups, low power, etc. The obvious answer to this is the ecu gremlins are getting out.

Normally the ecu gremlins are trapped inside your turbo system but what happens is they are able to escape through openings like leaky exhaust donuts, loose fittings, blown off throttle bodies, etc. What happens is they escape through these openings, then head for your ecu and will attack it! Once infiltrated they will make it so your ecu decides to not to send injector pulses, offsets timing, etc. This is how you get bad performing turbo kits.

Our best advise to avoid these gremlins is to keep them sealed inside your turbo system. If you feel your sled is getting them, double check all of your pipe joints, hose clamps, etc. A pressure test is a sure way to locate their excape paths. Once sealed the gremlins will remain trapped and will be unable to corrupt your ecu.

On a serious note, we had 2 customer installed turbo kits complaining of very poor performing sleds and dropped them off. A quick visual found that both had charge tubes that were clamped down poorly and had come off the throttle bodies. We mounted them properly and the sleds were back up and running awesome. Before you go and start freaking out wondering why your sled runs bad, PRESSURE TEST it, or better yet, just open your hood and look for loose or leaky connections. Hard to make power when your boost isn't making it to the motor.

Happy Boosting

Good info and very true.... IMO you should be putting new exhaust donought gaskets and springs in about every 500 miles. Same with primary spring and cam arm bushings

I also feel that new exhaust donuts and springs, new fuel filter (Pro), clean exh valves should be installed on all sleds when adding a turbo kit unless the sled is brand new. 200-500 miles is not new.

Also, these turbo's need all the air they can get. The addition of an SLP or FirenIce external intake should be mandatory. I feel they are mandatory on an NA motor.
