That sounds great! Can't wait till you get the updated tune in!
that IS the updated tune for the upgrades we put in!
(yes that video was taken at like 3am..sure his neighbors love him)
It REALLY feels like it hits a rev limiter at 3800-4000. Pulls pretty strong until that mark then just misses like crazy and rpms stall. We tried in D, tried holding it in first....can cruise at 3500 smooth as can be, press pedal tad bit more and rpms just 'bounce'.
Anyone have anything to check other then 'tune'. Which is what I'm leaning towards.
My 'scanner' can be touchy, but we were seeing like 31 degrees of knock retard at one point. This was on premium fuel, and those 'rich' codes coming up.
42lb injectors without a tune = most of your problem

Truck runs too good at idle-3500 for it to be something mechanical. It would be a more gradual, you can hold it in first gear at 3600 or so rpm and it feels stock, go up 100 rpm and it bounces like crazy, give it more gas and it just stays at same spot. My truck did same thing stock at 92mph or whatever.
not only that, but in park, i bought it to 4k and held it for about 3 seconds.. no misses
put it in drive.. get it up to 3800.. misses all over..
could it be they didnt account for my stall?
does this make sense?

Sounds like cracked spark plugs. My brothers truck did the same thing, at idle and very light load it would run fine, under load(50%-WOT) It would miss and pop. Might double check them, cheap insurance.
The LEDs looked like lasers on video, nice light show. :lol:
Truck sounded good, if it aint the plugs then maybe the tune just needs a once over. :)
