LG Headers-Dyno Tuned-Graph Enclosed
Well, I finally got my car with the Lg Headers dyno tuned. It might be 6 months or longer before I do a H/C and just wanted everything to be right. Guess I'm pleased with the final numbers but wish they were a little higher (who doesn't). I think with the 4:10's they are ok though.
I can feel the difference in torque. He used HP Tuners.
MODS---01 Coupe 6 Speed
Ghl Bullets
Halltech Stinger
LG Longtubes w/high flow cats
4:10 Gears
Final numbers were 338.9 HP and 350.5 Torque
(Isn't this about avg for headers with a tune?)

Good gains. Love the added power, it makes a big difference in the response of the car. I had installed a Vararam B2, Dynatech Headers/Cats/X-pipe, Magnaflow exhaust and a Dyno tune. pretty close results

Well, good numbers. But I hate to steer away from the topic. But I've been following some of the headers wars thread on which one headers is better than the other, and it seems like the later post with the dynatech headers got better numbers against the LG LT headers. Now I'm more confused as to what to get in the future. I don't go to the track. But I am looking for that extra ooomph on the street. That's why 3.42 gears and headers are part of my long term projects. Is there something I'm missing or is there just a difference in dyno and programming?

I asked them about this and they said it is what it is, they said others had said they thought their dyno was on the conservative side. I had same mods except for gear change. Maybe the plus or minus difference in dyno's. Beats me.
I can't wait to get my headers. Did you or someone else put them on?Edit - Just saw your message above. Looks like I'll be in the same ballpark as you once I get done.
Hey, we're having a dyno day 10/29 at Perf. Garage if you want to come hang out. I know you just had it dynoed, but you're more than welcome to do it iagain. I wanted to get one more baseline before i put the headers on.

If you are just looking to add SOTP permagrin
, then the Dynatech performance gain vs. cost is a winner in my books. If you are looking to run the car at the track, add a Head/Cam or Blower, and are competing against other cars in your class heads up then the extra 5 HP at $600 extra for LG's may be the right way to go. What ever you decide to do, I can gurantee you will not be disappointed. Have you read anywhere in all the Header wars, about someone who out and out hated their setup? I didn't think so! The only question to ask yourself is, what could I do with the extra money..... how about a Vararam
Good luck

Actually, LG LT headers drop there price a couple of hundred dollars, they can be had for $1695 now as opposed to $1895. I think this is competitive pricing wise. I've seen some Dynatech pricing around $1,600 as well and some of the cheapest I've seen are around 1,400. But since I'm on a budget, I just might go with Dynatech unless the new LG street headers comes out cheaper with competitive numbers as well.

[QUOTE=JR_VETTE]Where at in Nashville? Performance Garage? My sig has my number from there. VERY close #'s if that's the case! I can't wait to get my headers. Did you or someone else put them on?

Hey, we're having a dyno day 10/29 at Perf. Garage if you want to come hang out. I know you just had it dynoed, but you're more than welcome to do it iagain. I wanted to get one more baseline before i put the headers on.
I had forum member Vettes4fun, Todd Vinson of Vinson Automotive in Mayfield Ky (about 20 miles from here) do the install on the headers. Good guy and did a great job. I might make it down for the dyno day, just have to wait until it's get's a little closer to know for sure. Oh, get some headers, if anything they make the car sound awesome.

About right for your mods, my 99 MN6 with a Blackwing and FLP LT, high flow cats, x-pipe and Corsa Indy's jumped from 292 to 325 RWHP and that was without a tune.
I believe I could have gained another 10 HP with a tune.
