Fisrt sorry for my bad english (from Switzerland)... but I'll try to explain my problem: So recently I've had starting issue with my 3 MPS. When the car sits for about 2-3hours, there is a hesitation with start up. I have to crank it at least twice. I've checked fuel pressure after turning key...

Up!! Have you fixed your issue tfarmer69? I also have same problem and don't know what to do! Fuel pressure is also low (about 50psi) before starting the car...

Hi, I'm looking for a Cobb SRI MS3 for ready to ship to Switzerland!! Thanks

Hi! I'm looking for a manifold for MS3 (used or new) asap. PM me if you've got one ;) Thanks

I wouldn't care about negative trims @ idle. Mine is -18% idle but 0% WOT. Open loop is more important for me.

I'm sure there's some gains with CBE, with mine I got +300whp without DP, only TP+CBE, Intake, TMIC and custom tune. That's why I'd like to know if Hypertech has done some EGT tests with and without CBE?

Emailed for DP ;)

Have you measured EGT after catback installed? I'm curious to know the result...

Thanks Derrick ;) I'm waiting for the softer spring, and remap if it doesn't work. I had Piasini tune before but now we've done a custom tune with EcuEdit on my car and works great ;)

I put back stock bpv and No knock. So it was because of the bpv

I forgot to tell that I've got the "hard" spring in. The guy didn't send to softer spring so I couldn't test it. Do you think harder spring could cause Knock at WOT? I've already put back stock bpv and I'll see tomorrow if it's ok or not

Only at WOT in 4-5 gears

Hi!! I installed used SU Turbosmart bpv today and after couple WOT I get some 4-5 KR with same boost as stock bpv. Ltft doesn't change, do you think there's some leak or problem with bpv. I've checked everything and it seems ok. Thanks

Pm'ed for the bpv ;)

Yes me ;) I have a custom tune with this soft on my car, and pulls really hard!!

63mm

We also have a little muffler near the exhaust tip, like MS3. I've installed Corksport CBE, and I really can fell the difference in power!! So there's a restriction on CBE on 3 MPS!! And I really like the sound, it's quite louder when engine is cold but it's ok after. I've also have a SU test...

I also have the same issue in 4 and 5th gears after 4000rpm after adding a CAI. With the stock airbox, clutch didn't slip...

Thanks MSMS3, I really want to get a DP but I've seen installation is quite hard so I prefer getting a Corksport CBE instead, and re-tune again ;) Here's a pictures of a 3 MPS Stock CBE:

Ok, on stock tune gain is minimal, but have you already tried on 18psi or more with custom tune. I think you can slittly increase boost in higher rpm with a 3" cbe. Look at this article, the gain from Vibrand 3" CBE (with catted TP) is not as minimal that you said. Is more than the donwpipe...
