Boosted 4.3 bog at wot.

[Bandit gs]

Tuning my brothers boosted Xtreme 4.3 with a Vortech, custom comp cam, headers and exhaust. I have the maf dialed in perfect, VE tuned, timing decent and it runs a clean 11.5-12.0 at WOT.

On the 2-3 shift, right after it shifts it falls on its face. Foot planted it just bogs and the check engine light blinks, let out of it and then back on and it goes. Throws a missfire code. Anybody have any ideas? Plugs are gapped a 35 like Votech recommends. Runs a dual pump setup that Vortech shipped with the kit.

How about posting the tune file and the log so we can look at it?

I typically never save them. I can I guess, it's only the 2-3 shift, don't have a boost gauge hooked up yet but I'd guess 5 psi or so. Right around the shift service light blinks, truck falls on its face, let out of the throttle get back on it and it shifts and goes again. 1-2 and 3-4 shifts are fine.

Vortech is worthless - I'd never buy from them again.
