Ok here is a list of what i have done to the car..
Cone filter
AMS base flash
UR full turbo back w/ test pipe
AMS IC and UICP

The problem:
when I jump down on the throttle the car seem as if its struggling for power..it wants to go but just doesn't pull hard enough it kind of spudders. I pulled the spark plugs and they are ok...I am on my third set btw...I change them out pretty often. Another thing I noticed is that when I am under full bost the ASC light will come on I am wondering if this has something to do with getting re-tuned or not... the engine seems as though its pulling timing for no reason. I had this problem a week before I threw on the FMIC..should I get the car retuned?..

Mi...20,000K btw..

 

i had this same problem i delt with it for about 6 months after i got my car tuned
a couple of weeks ago i installed a bunch of new parts and went back for a retune and mentioned this to my tuner he made a couple of changes to a few dif tables and its fixed no more asc light so yes i do beleive that its in your tune and can be fixed with a retune

 

It more then likely is your tune. You're tuned to get the most out of a stock vehicle, and now that you have more then likely highered your VE, and still set up for "stock", something in feedback isn't happy.

 

Thanks guys...it's just weird cause I've been running the car like this since august...and now it's just holding back..and that darn ASC light comes on, again just started doing that about a week ago.....I hope and pray it's the tune..Man now I really can't wait to see what it does..what kind of numbers are you guys making..if you don't mind me asking..

 

im making 370 ish right now hope to be well into the 400s very soon when i get retuned with the meth on

 

What are your mods?

 

You aren't getting over 400whp without meth?

 

Call AMS they gave you a base tune? They can straighten you out. Its a tuning issue with airflow versus torque limitation.

 

I've had that base tune since august..but I didn't have the mods I have on the car now..so you think this custom flash will increase hp..dramatically or just a little..

 

You just need the limiters increased. A flash is needed and will make a big difference. AMS can take care of you since you are in there neck of the woods. I am almost positive it will solve your issue.

 

Thanks, I have an appointment scheduled for tomorrow..I will post the results ASAP..just sucks cause eggs cause I know the car is faster...

 

what code are you throwing? U0184? Mine lights up after my custom tune. I still need to get it fixed.

 

No I'm not throwing any codes..it just spudders up top..and then the ASC light comes on...I will let you know the results in a few hours..I hope my to unleash the fury on the dyno..and get this problem fix... I will post result in a few hours I am on my way to the tuner as we speak..
