Default Questions about PPE Xcelerator Standard?(LB7)

I scored me a hell of a deal last night. Someone local had a Brand New PPE still in shrink wrap and I picked it up for $150. I know PPE are next best thing to EFI LIVE in most peoples opioins. Im sure my questions been asked before. But I have searched till I got lazy so I thought I would post them.

1) What is a good daily driving stage to use, 1,2,3,4,5?

2) What is a good stage for towing?

3) Any do's or dont's with this system?

4) I have a lift with 35in tires. When I got the truck it already had a SUPERLIFT TRUSPEED SPEED SENSOR CALIBRATOR. Now if I install the program but dont change the tire size cause with the inline SUPERLIFT TRUSPEED SPEED SENSOR CALIBRATOR it makes my speedo that more off. If I dont change the size with the PPE will that throw my shift points off?

And maybe any others q/a I might be forgetting or other suggestions.

My PC(at work ) times out before I can update my sig. So this is my specs

02 LB7
4in Straight Pipe
6in Lift w/35in tires
Boost Valve
Air Box mod
Guages
Other wise stock.
thanks for the help guys.

On my LLY
Daily driving tune: 90 or 120.
Towing: 90
I would take off the Superlift Speed thing and use PPE for that.
Do's & Don'ts: Don't run the Higher levels on a stock tranny.
Also look into some gauges too.

Right on. So what do you think about the trans quick relearn? How long/miles do you go before you can give her hell again? I like to mash on it here and there.

Also before I installed it my boost was around 23-24lbs with the boost controller I have. i just got back from a drive and noticed a huge increase in spool up time on Lvl2 but my boost stayed the same. Does this programer raise boost at all?

it will give you more boost on the higher levels but with the stock waste gate it will try to limit it, get a ppoe boost increase valve and it will go up more

Are the 40/90/120 tunes on the economy the same 40/90/120 tunes on level 1-3 on the Standard Xcelerator? I have a buddy who wants to sell one. I have a 2001 CC Allsion with 4" exhaust stock tranny, K&N drop in flat air cleaner and PPE boost thing in the line. 265 75R 16 tires. I plow and daily drive with it..
