i have a 08 turbo, just installed a mpx catted downpipe and catback exhaust, and a K & N SRI, I also have GMS1, the car idles very rough and when driving at WOT in 2nd and 3rd I dont hit 20 psi like I used to with just GMS1 right away, its like a lag to get to 20 psi. I know im going to probably need a tune, and am intersted in trifecta, but would rather go to a dealer to have it installed, and I cant get in touch with any on long island. I already checked the forum for trifecta dealers and cant get a hold of anyone. If anyone can please tell me where to go on long island for a tune, and a rough price on this as well, it would be greatly apprechiated. If I ordered it from the the site I wouldnt know how to install it or "data log" or whatever, im not very car savy, thank you

 

if u have a lap top, or a friend has one that u can borrow, just order it right from vince at trifecta. thats what i did. its crazy simple, u basically plug it into ur obdII port and hit go.

 

If your car is having problems now, then you need to get it fixed before you screw around with it any more.

Would you go skydiving if you had a broken leg?

 

Installing these items shouldnt cause you car to run like that without a tune. You might have left somthing unplugged or loose. The new down pipe could cause it to run like this if it's clogged. Was it used? If not it's unlikely. New knn filters come with too much oil from the factory. You may have got oil on MAF sensor. You can buy maf cleaners. Be very careful when cleaning the maf. Don't use too much cleaner. You should eventually set a code. You may already have one set, even though the MIL is not on yet. Some codes have to fail contiuously on differnt ignition cycles to turn on the MIL. I would scan for dtc's. And i wouldnt tune it untill you fix the problem. Other wise data logs are gonna be f'd up
