Any extra help on the fuel system to use full e85? Meth injection?

Guys, does anybody have problems switching 1->2 when starts from full stop on D1 and D2? No LC just hit the gas. I don't know how to correctly describe it but it's like kick or punch on switching with power loss and bad timing. Other gears is ok. When on D3 it's smooth and no troubles.
Flashed to stock and test - ok on D1-D2-D3.
Didn't noticed that issue before.
What can it be? I'm on Stage 1 93.

Update: just done a few tests and it seems that it's wheel slipping on 1->2 switch and DSC trying to stops it and then power loss and so on. MDM mode - the same issue. DSC off and all good on D1-D2-D3.

The main question - why it's only on D1-D2 and D3 is still smooth?

I'll just toss this out there. D1 & D2 (unless my knowledge is aged some) are the selections that the torque converter is allowed to engage. D3 and up are lock-up only.

Can you explain please in details what does mean "lock-up only"?

Torque converter allows for slippage between the engine and transmission output. That's what allows you to stop completely and keep the engine running with an automatic transmission.
D1 (naturally) would need this. D2 also has it as you can go to S2 at a stop and when you take off, less chance of torque slippage on road surface with questionable traction (like ice). At a stop, though, you cannot shift into S3 and above as there's no torque converter slippage with D(S)3 and higher. D3 - D8 have the torque converter locked, so to speak. This is more efficient mileage-wise and you generally don't need the advantages associated with the torque converter being allowed to "slip" (which produces more output torque).

It seems that we missunderstood each other. ) When I wrote D1-D2-D3 I mean transmisson mode, not gears. We have 3 automatic modes (D1-D2-D3) and 3 manual modes (S1-S2-S3). I have troubles in switching from 1 to 2 gear only in D1 or D2 (S1 and S2 too) transmisson mode. While in D3 (S3) everything is ok.

Oh. Soon to be better edumacated ...

It's much more helpful to do a single pull throughout the rev range in either 3rd or 4th gear, rather than shifting through all the gears. Pretend you're on a dyno, but pay attention to whats ahead of you haha. You're only capturing the top end of the rev range essentially....

Thanks- not sure where I got the impression that I should run through 3,4, and 5th.
