I had this video on my camera for probably 6 months and finally had time to download on youtube today.
You can see the difference from the car tuned and not tuned. Actually to be 100% fair we did have a few more issues then just the tune, but this gives you an idea. For some off reason I mentioned in the video that I had Borla mufflers which isnt true at all. It's obvious those are the B&B's. I was planning on replacing the reasonator last fall with the B&B x-pipe, but it didnt play out. A have a few projects in the spring, and one is the x-pipe which will make the exhaust flow better. That reasonator necks down to either 2.25 or 2.50 inches. I am also debating cut outs or muffler eliminators for mild to wild!! Not too hard to tell which video is which. The smoke in the untuned sort to speak was the break in oil. Many of you know the mods so I wont explain but last dyno was 434rwhp/470rwhp and that will only go north with better flowing exhaust, and more tuning! Take care! http://www.youtube.com/watch?v=NPLT_VmK-sg http://www.youtube.com/watch?v=mJP1UGJCWqI |

Sounds great! Any idea what your timing was at idle before and after the tuning?
I have duals on mine with stock LT1 mufflers, but no resonator or X pipe or anything. Mine sounds very free flowing, kind of airy almost. An X pipe is on my to do list. |

I have a vid of it idling with the T trim, not an exhaust vid, just a supercharger whistling vid. I'll see if I can get it posted to youtube and post the link. I've never posted a vid anywhere so it might take some work on my part!

In your original post you say it made 434 RWHP / 470 RWHP.
Is that the difference between the tunes, or did you mean to say 470 RWTQ? |

My mistake. Yes I meant to say 434rwhp/470rwtq. Realistically I would be very happy to see approx. 450rwhp and 485rwtq after the dust settles..... When its fully tuned and the x-pipe in place, I will post the dyno sheet. I dont see a point right now. |
