You may want to leave it alone or go something smaller than 3". With the TP on the car and a 3" you may get bad boost creep. Search for Greddy boost creep. You could just change out the mufflers on the stock system if you want. I think the best set up for the greddy kit exhaust is a Berk HFC and a Greddy 70MM single or the invidia Dual V3. Seem to be the most flow and HP with out too much creep. I hope this helps

 

thanks revenge. I was thinking about just welding on the mufflers, but I think that might kind of defeat the purpose of even having the mufflers. Prob would not gain much if not anything. Since I have already spent so much on the kit and still need to tune the thing I don't have the cash to swap out for a whole new exaust. Would a manual boost controller help at all?? I looked at the boost creep pages and people were saying that the internal wastegate is the problem. This is kind of a hard situation with this kit because everyone says that turbo cars work best with open flow , but this kit doesn't want that. I guess my TP is throwing things off too though and unfortunately I don't have it anymore. At WOT right now I stay at around 8psi or so. Any further assistance would be greatly appreciated...thanks

 

IMO most of the boost creep is due to the tune and a majority can be solved with tuning over the stock greddy tune.

 

how can you tune out CREEP?, its a mechanical issue, not really a software, type of thing, maybe pull timing at the RPM it starts to creep at?

anyway I have the Invidiia V3, crept out of control with a test pipe but holds steady even in 10F weather with the berk HFC

 

So basically my problem is, I would like to make my exaust piping (maybe 3" or so) but I am worried about creep. Do you guys think I should try to tune it with the TP or should I just upgrade right now????? So Joey so you recomend a berk HFC, Do you think that would help? How bad was " Out of conrol"???? Is there any other ways you guys have worked around this? And if I did decide to change it then should I put the resonator back in or should I run it straight back?

 

My creep was bad enough to hit 20PSI . I would do one of two things, get any type of aftermarket exhaust, (for sound mostly), and throw on the Berk HFCm you wont creep, or do what I should of done and leave the exhaust stock and then throw in a Test Pipe, the stock Exhaust is designed very well

 

Thanks for the Pressure sensor install tip!

 

WOW. 20 PSI. Thats crazy. I think I am just going to keep the stock exaust on, but I might swap out the mufflers since I already bought them. Hopefully they don't make it sound like krap though. What did you have your A/F set to JOEY? I heard around 12-12.5 is good. I am kinda worried about tuning this thing though since I am in BC. Hopefully I can find someone with some experience with emanage..Thanks for your help JOEY..

 

Hey everyone. My current set up is just a greddy turbo with a megan test-pipe. I have a AEM air fuel set-up as well. When i started the car today my a\f gauge was readingany where from 14 to 17 at idle and then would settle down and when i reved it kinda fluttering all over the place. When i give it steady throttle it stays at around 14. It is not tuned yet...... Could I make it the drive to the tuner shop if i don't boost or is this too dangerous???

 

i have 2 now, 1 pcv, 1 breather.
