get the 1+ flash, it makes a lot more torque and will hold it a tad bit longer than stage 1....i barely noticed the stage 1 trial...you can PM manguyen on audizine for the injectors(much cheaper than APR)... FMIC or upgraded sidemount IC will be your next best bang the for the buck followed by exhaust/test pipe and TIP

 

I noticed a big change with the Stage 1 trial software from APR. But then went to 1+ a couple months later, so i dont remember the difference. But deffinatly worth it!

 

What about chipping a 1.8T CVT? Is that worth it?

 

I've been wanting to get this mod for a while and finally am looking into the APR Stage I+. I was looking at the injectors installation document and I'm not clear about one thing. Do you need to rethread the injector seats for the APR injectors? Check out step 8 in the .pdf: http://www.goapr.com/Audi/support/injectors.pdf

Any help form the guys that have installed the injectors themselves would be appreciated.

 

i havent installed them but in the pdf it says if you have the bosch injectors, then to skip to step 11 which means you wouldnt have to with the bosch ones

 

i went with the apr stage 1 back in jan of this year... it's a night and day difference. i got the cat delete file from them so i could run my test pipe with no cel.....the total i was charged was $550 with tax. and it is def noticeable... u go from 8psi or so stock, to 18psi. i first noticed that where the stock car used to stop pulling, the stage 1 car keeps on going. i got the stage 1 instead of the 1+ program because it was cheaper, and it gives me a chance to enjoy it like it is and by the time i start to get bored, i will have saved up enough to go to 1+. i found 380cc injectors online for $248 and plan on using them w/ the 1+. and for gas mileage, when i'm driving normal, i get about 25 around town and 33+ on the highway cruising @ 65 in 5th gear (god i wish it was a 6spd, 65mph@3000rpm!!!)

 

stage 1 or 1+ flash is the same price, they will charge you if you upgrade to 1+ though...

APR software seems to be happiest with the OEM tt225 386cc injectors, 380cc ones seem to have a few idle issues and cold start problems... manguyen on audizine sells they tt225 bosch injectors for around $350 shipped
