u can buy the TRD tach and go up to 10..
and i think its all depend if ur car is modd, or tuned
and some car can go up to like 9ish or somethin
and once again its all depend if ur car is stock or not..
my turbo kick in at 5 which is slow but if i get it retune
and put autronic ecu in it and do a dyno tune
then i think my turbo will kick in earlier (maybe im wrong)
im kinda new with theses stuff too

or just put 200shot of nos and u will be set to go:gotnos:

Maximum 6 kinds of data can be shown on the screen at the same time. (Please note that temperature sensors, pressure sensors, and A/F unit are optional items.)" i donno just give me a heads up on what type of gauges i should go for and some links so i can buy some like whatever ones that are important, thanx

All you really need is a boost gauge, for most situations. If you're going to be your own tuning with a standalone ecu (or piggybacks), you could use a wideband O2 and EGT...

The oem TT, in sequential mode (that's how they come stock) kick in at about 2250 rpms. The second 'stage' kicks in at about 3500 rpms.

If you upgrade to a big single turbo, then the bigger you go, the later it'll spool in the rpm band.

The oem rev limit is 6800. With an aftermarket (standalone) ecu, you can set your rev limit to whatever you want - like (for example) 7500rpms with the oem valve springs, or (again, for example) 9000+ rpms with aftermarket dual valve springs and a built bottom end.

since i have no clue where to start and what to do to the car slowly piece by piece getting it upgraded

Slowly piece by piece is the best way, imho. Don't rush it, and learn as much as possible along the way. Also, enjoy each horsepower upgrade, and use each improvement to improve your driving skills and your ability to handle each incremental increase in power.

reason y i bought 15 40 cuz they ran out of 10 30 last time lol
really Amsoil is good? never that brand before
i tho royal purple is the best:eek3:

Yes, Amsoil is the best by a good margin, imho. However, if you're not going to be roadracing, you may not need to worry about that difference. Any 'regular' full synthetic is just fine for street use in a TT.

piggyback hooks into the stock and adds to it, standalone works by itself overriding the stock computer all together. i think thats it

Actually, even more than overriding, the standalone fully replaces the oem ecu, in most cases.
