I have a 06 charger 5.7 hemi and I got this bbk 90 mm throttle body which they said was plug and play that's a joke but anyways . I keep getting high idle alarm p507 what do I have to do to get this unit to work right in my car? and thanks for your help. Mark

 

when i got my fastman tb he said i might have to turn key to on, don't start, push accelerator slowly to the floor taking 10 sec or more, then start and try. maybe that will work for you.

 

I tried what u said but no luck. thanks for your time Mark

 

You might consider looking into an aftermarket tune, and do some research on it. Like Diablo Sport Predator. You might want to contact them and see if their tuner can adjust for a bored throttle body, since they can control Throttle response.

 

hemifever can set you up with a tune for your setup

 

A 90mm TB is an overkill matched to a stock 5.7 intake manifold. Unfortunately these fall under the same myth as do CAI systems, false performance gains. If you want to avoid a CMR tune, downgrade to a 85mm.

Yes you'll have a crisper throttle response, however the only potential gains from a bored TB will require additional support mods... Upgraded intake manifold, 6.1 ported, for one, plus as mentioned additional tuning, and however farther your wallet allows from there.

I'm running a 85mm, with stage II heads, and stage II 268 Comp Cam, and bolt-ons all the way back. In theory, with a stock intake manifold, I never noticed much difference swapping the TB, just a louder idle, and crisper throttle response.

 

I love to get a 85mm u know any how would trade? hey thanks for your time guys Mark
