chips, chips, and more chips...

[Grannynational]

I have tried the thrasher 93 and the jay carter 93 street chips and bolth chips dont spool up as fast as my stock chip.

What happens is I have to turn the boost down with the aftermarket chips to keep my nice and happy 15# of boost. There is no spring presure on the waste gate with the after market chips. but with the stock chip It allows me to shorten the wastegate actuator rod so I have spring pressure on the wastegate and the stocker chip spools up much quicker and feels more powerfull at my safe and happy 15#. my wastegate actuator is new along with my Y hose witch is properlly hooked up and the boost seleniod.
any Ideas??

Primarilly because those aftermarket chips have more boost in them, hence you have to lengthen the rod, which, if too long will cause the slower spool up. Kind of a "nasty circle"

Why are you running so low of boost with the Thrasher?
It is a low timing high boost chip.
I can run 17-19 on pump gas with this chip.
Not sure on the JC chip.
The low timing on the Thrasher makes it feel less powerfull on the low end.

If the Jay Carter chip is a variable timing chip, it should pull harder all around than the Thrasher. It goes higher timing in the low end while the turbo is spooling, then backs it off to run high boost on the top.

I might be wrong but I think you have to have,T-Link with boost sensing to run JC variable timing chips.

Dave, can he use the BoostCommander to defeat the programmed boost? I know you can if you ignore the ecm command as we do with the ME but I forget what it can do if hooked up normally. You can bypass it when hooked up normally, can't you?

[TurboJim]

What Dave said. You need to preload the flapper or it'll open too easy causing lag. The BoostC will only help if its borderline. The rough correct minimum setting should require you to pull the actuator ~1/8" to get it on the flapper. Any less and it'll prolly lag.
