upgrades
 

well i finally got the highflow cat put on my car, had the u-bend delete done about a month ago, then had the highflow cat put on on monday, very happy with it now

so right now my car has the ubend deleted, 3"highflow stainless cat, no resonator. sounds really good, not very much noise at all, i didn't want it loud as its just the v6

i think all i'm going to do is put a cold air intake on it and a smaller supercharger pulley in the spring and thats probably about it, i can't think of anything else really thats not big big dollars to up the horse power a little

RE: upgrades
 

How much power did you gain from the u-bend delete and the highflow? If any at all.

What about a PCM upgrade? That would improve power a small amount and delete speed limiters;).

A new throttle body spacer could potentially give you some more horsepower, but some disagree and there will probably be any argument about it after i say that.

yah there's a lot of arguments over throttle body spacers, i dont know if you really get anything out of them

i really noticed the difference on the ubend delete and the highflow cat, mine is supercharged and you usta have to wait for a couple seconds before you would feel response from the peddle, but not anymore, its instant now

very happy with those 2 upgrades, i would never have thought about doing that if it wasnt for the website

Make sure you get a scanner before you get the pulley drop. My stock L67 had 2* of KR, dropping the pulley made it much worse. I'm waiting on my DHP programmer to come in the mail so I can start working on that.

RE: upgrades
 

2* OF KR????? whats that?

i didn't know you needed to do any pcm work if you got a smaller supercharger pulley
