So I just wanted to report in on how much smoother the Lund tune is. I've been running the Bama tune for quite a while now and have grown tired of how hard it can make the car to drive sometimes.
The throttle seemed to only have an on or off, no easing into it.
If you get off the gas while staying in gear (any gear) the car rather violently jerks upon decel.
I was hesitant to spend $200 on just 1 tune, but I figured once I go FI i'll just fork over the other half of the $450 and have Jon tune it then too.
The car drive so much smoother now, idles much smoother, and feels just as quick.
If you take a look at these 2 datalogs you can see how erratic the bama one is compared to the Lund one. Under WOT the Lund curves are nice and flat. Blue is timing, yellow is A/F. Both runs were either 2-3rd gear or 3-4th. I don't remember.
Bama;

Lund;

The peak #'s all around (a/f @ .84-.86 & timing @ 28.5 max) are really close between the two but it makes a huge difference driveability wise whatever Lund does.
Another note, yes timing is up there but I am running a lower c/r.
Scary thing is that Lund knew this when writing the tune and added timing for that reason. Bama did not know this and this was a tune designed for a stock c/r motor. Seems kinda high unless you knew the customer had a lower c/r.:dunno
Anyways, not trying to bash Bama. I did not ever attempt to have them revise the tune based on datalogs. I'm sure they could have made it better. It's just that Lund seems to have got it right from the get go.
