I would expect stuff like this would be more likely to pop up with all the different UEL header lengths. EL is EL, shouldn't matter so much if it's long or short tube I would think.

Hypothetically speaking though...is it even possible to miss that dip if I'm driving at higher RPM's? If the dyno claims it dipped in 5th, then I should be able to replicate it from 4000rpms and upwards, right? .ck |

I would think you should be able to feel it in 3rd and 4th easily, maybe even 2nd. Your right that it's possible you always drive around it, just like you can drive around the torque dip.

I'll echo the above, the drop is far more sever than the stock dip, it would feel like the car hesitates every time you run through it. You would notice it.
Did you flash the tune immediately before hitting the dyno? Any chance the LTFT hadn't settled, causing a lean situation and possible knock correction to occur? That could cause a drop similar to that.

Just saw this thread now... That torque dip you show should be very noticeable when driving, that's worse than the stock dip..... Curious to see results of this. I am OFT stage 2 uel. Love it!

I know this is an older tune, but I can still feel it on the newest maps(It's not as bad, but still there). I had somewhat the same issue around 4500rpm. WOT the car would just stop accelerating for a bit, then keep going. Datazip WOT Log
at 4500 rpm (Almost on the dot) you can see the rpm's stagnate, then pick back up. This happens more often in 5th and 6th gear. Even this is extremely noticeable; so I would assume if the car dropped as the dyno showed, he would notice it.

Am i the only one who looks at that and thinks its just timing being pulled and then ramped back in? Thats how it looks on LS powered cars. In a perfect world that part of the timing map would be fixed but isnt this an off the shelf canned tune in a holy crap epic amount of load that you'd never actually subject the car to?

If it was an extended pull the load on the engine is higher, and it's possible that this increased load is causing some knock at that RPM / Load.
