Stage 3+ questions RS2?

[AudiI5UrS4]

Hi all I have a couple more performance questions, I have been doing a lot of research but coming up with some conflictions. 1.)My sidemount that I have been having problems with getting VERY heatsoaked but i've read a lot of posts where practically everyone goes to this stage 3 RS2 on the stock smic and keeps the smic...is there something I am missing..but my question is I want to put a fmic on and if anyone has a good way of routing the piping? 2.)All I need to complete the stage 3 RS2 upgrade is the injectors and the tune but I keep finding that they ADU injectors are bigger but then I have found a couple different spread sheets showing the the ANN and ADU @ 3 bar flow the same as below in the spreadsheet: Obviously ANN 0-280-150-984 ADU 0-280-150-951 http://users.erols.com/srweiss/tableifc.htm But then I see this below also? AAN injectors Run at 4.0 bar FPR in S4/S6 Bosch 0 280 150 951 Audi 034 906 031B 280 cc/ min @ 3.0 bar 315 cc/ min @ 3.8 bar 323 cc/ min @ 4.0 bar 361 cc/ min @ 5.0 bar ADU (RS2) Injectors Run at 3.8 bar FPR in RS2 Bosch 0 280 150 984 Audi 034 906 031F Porsche ? 360 cc/ min @ 3.0 bar 405 cc/ min @ 3.8 bar 416 cc/ min @ 4.0 bar 465 cc/ min @ 5.0 bar 3.)I have been trying to repeatedly get a hold of Steve Eiche at Shadetree Software (which I found out with the help of UrS4boy is my tuning company) with no luck. I am thinking I want to end up putting on a 3076 on but want to talk about cost of tuning but for the mean while just to get the stage 3+ tune put on or will the ecu be able to adapt to the new fuel tables or must it be told by the chips? But I wanna gain maximum hp/tq of course so should I just repay for a different company or...? Again thanks for all help, you guys are great!
