to the OP. the TiAL's will get you better spool time than the VAST kits, hands down. and the VAST kits are one of the best deals out there, and compared to the 605's, they have a lot more uncapped power so to speak, much more upside and potential. but to get there you need to build your heads and bottom end. which you should also do with the TiAL's, as they also make enough power to break stuff easily. i know of 4 or 5 guys with 605's and 770's, all with power starting from 500whp to 585whp on pump. many happy customers. and there are many people with VAST gt kits that are putting down great numbers and walking cars, hell VAST's work speaks for itself. keep an open mind when looking at either kit, decide what you want in either a DD or a weekend warrior and make a decision based on true facts backed up by logs and personnal experiences by various owners of different setups. i like this forum, but seriously you should get on audizine, much more people to discuss these with and many various setups/platforms to note.

the vast kit does seem to be the logical kit to go with seing as nothing has to be torn up on the vehicle, its also allot cheaper with good numbers in the end. where are they located and is there a waiting list or anything to get your vehicle in there? and how long does it usualy take for them to install, dyno, tune?

Tials are Nice but there not great. Its cool if you think you can flow 500whp on your stock manfiolds and not have an issue. Try logging your car next time and tell me what Cyl 5 and 1 do. Any car S4 or other wise. is going to have issues with short runners and small manifold size. The issues are back flow pressure

For the money one kit seems to make more sense the GT kit..and come in with what the OP was asking for. If you can get a header kit over a Tial kit then the tial kit looks less and less impressive. Let alone the tial dynos are less then impressive if you don't run 30+lbs of boost. The tial cars need to run 30+lbs of boost to make what the GT kits make at less then 25lbs of boost. Tial kits don't do much better then RS6 turbos. maybe if you get the 770 kit but at that point its retarded not to just get a REAL GT turbo.

Ive raced 3 tial 660 kits with my Automatic car at waterfest and all of them lost bad. Ive never heard good feed back from Tial owners that are not posting on the net.. This is why I wouldn't suggest them to the OP.

I know one guy with Tials and he thinks there junk.. I know two other guys that got them and Tial tightened the waste gate too tight and he ended up running too much boost and hurting a rod trying to figgure it out. From everyone Ive talked to and read on the net. If you don't run 30lbs of boost on Tials there not really impressive.

and Tials don't spool faster the GT's try doing more searching. There the same.




I don't know the vast guys personally but they have always been very nice and have lots of S4's there. that always makes me feel better.

It always looks like this when I go there.



So I would expect a wait but there usually quick to get your car in and if your able to pay your bill and don't need for them to take there time I think there quick. They did my RS6's in 3 days. I know they did a GT kit on my buddys car in less then 1 week.

Vast doesn't have a dyno but they use one if customers ask for it. The tunes they make are for the road so they tune for it. I like that approach better then just throwing it on a dyno and calling it a day. Also at this point these cars shouldn't me a mystery any more to companys like vast. They have hundreds and hundreds of tunes out there for the 2.7 so I would think they have most of it worked out.
