I have not installed anything but am going to intsall
1. Cobb Turboback exhaust
2. Cobb Turbo inlet
3. cobb SRI
4. HKS BPV
5. SU TMIC
My questions are these:
1. Will this run fine on the factory computer?
2. Do i Need a HPFP? Or is it only safer to have it?
3. Will my car boost the same or will it be diff?
 
*without having specific speed3 knowledge*
the factory ecu's on all cars are designed to re-adjust themselves within 10-15% of the factory tune for optium performance. The exhaust might let you spike more, the tsmic and sai will reduce IAT's which will provide better combustion and more power, but probaly at the cost of a few PSI. the eBC on the speed 3 might be able to be adjusted to allow more PSI, but I'm unsure if it will automaticly adjust for the exhaust or not.
 
car will probably run good but is safer with a tune and i would get one. Your boost will most likely increase to ~18psi. i would get the pump too, always better to be safe than stood on the side of the road with your thumb up.

If i would really be safer with tune then ill get the hpfp and the standback from CPE and have them tune it for me cause they are 3 hours away
 
just wondering whwere you got your cobb inlet and how much was it

cobb inlet wont be out till the 30th. i posted simply what im goign to be installing. that is in the summer. im in pa, it freezing out, ill be purchasing it along with the SU TMIC. Im gunna get it from Mark at street UNit
 
I would think that you need a high pressure fuel pump.

i have internals that i may be taking out and uninstalling soon if you're interested.
 
run ok...

1) yes it will run on a stock tune but i wouldnt push it to much because with that setup you will be running alittle more boost and you will probably run into fuel cut from the computer
2) yes a high flow fuel pump is always a safe route to go. to much fuel is better then not enough.
3) You usually will gain about 2 psi doing all that.

I would really recommend getting step colder plugs and a tune before you push it too hard.
 
if youre serious, get a fuel pump, you really will not regret it, its one of the best things you can do for this car. i would get an accessport or standback too, a less than perfect tune is better than no tune.
 
you WILL boost cut with that setup. you WILL fuel cut with that setup. Things you need

On the cheap-
Fuel pump internals
Map clamp
Manual boost controller

Doing it RIGHT!<-----This is the way to go for sure
Fuel pump internals or CP-E HPFP<--Recommended
Standback v2<--Recommended or Cobb AP
Step colder plugs

As to the standback vs cobb argument, Ive had both, and if you are going to be running in cold weather or doing mods outside of the OTS maps and aren't near washington/texas, you will have a much better tune with the standback.
