ls6 intake, hooker longtubes, tsp ory, magnaflow So last week I installed a ls6 intake on my car and felt a huge difference. The car ran really strong and felt better than when I installed the 4:10's I couldn't keep first and second from spinning for as long as i kept my foot in it. Started Sunday with installing hookers long tube headers, Texas speed ory and magnaflow catback and now it feels no where at responsive or fast. It sure as help doesn't roast my tires like it used to. No check engine light as of now, any thoughts?

im not 100% sure, but you may need a tune at this point. Youre moving alot more air then you use to, so my guess is that its running a little lean, and a tune would help it out. Im sure more members will come in here with there thoughts.

I just recently also had an LS6 intake insalled along with some Edelbrock stepped LT's, and TSP ORY. AFAIK, the car is still on a stock tune although I do have a feeling my car was at one point de-modded before the previously owner traded it in so I cannot be 100% sure.
After having the above mods installed, my car pulls like a damn freight train after I hit about 4K rpms. The issue with mine is, it actually feels much slower/less responsive at lower rpms which to me says, I probably do in fact need at least a mail order tune. I spoke with speed inc and they seemed willing to cut me a deal for a dyno tune, but with heads/cam planned in the near future, I'm not sure I want to part with that cash right now. I'd suggest you install the bolt ons and see how the car feels. You can decide weather to tune it afterwards. Your service engine light should eventually come on however.

okay so I stopped by my cousins work to put this thing on a lift and have a look at whats going on( vibration from exhaust on the frame somewhere) and where it was hitting. Turns out all 3 of my mounts are bad and everything is sagging causing the headers to lay on the k member. After talking with him for a minute he tells me that the vibration will cause the knock sensors to pull lots of timing and is the cause of my power loss or no increase. so as a temporary "fix" to test this it now runs night and day better. It will spin through 1st 2nd and into 3rd a ways before catching traction. :-)

I definitely want to get it tuned, just a matter of when. I'm very hesitant on any mail order tunes and cant see them being as good as a dyno tune by a good local shop. will cost me more but could be worth it though. any thoughts on this?
On a different note, its track time tomorrow night and will have some new numbers. very curious to see what new numbers and MPH are
