Got my intake yesterday and installed it. Took me 2 hours following the great instructions from LRS.

This thing is huge. Looks like a composite tunnel ram for an old FE or something. Check out the valley! Engine burritos hell... could cook a 15 pound turkey in there! The pics don't do it justice.

I went with a BBR tune. I have gotten 3 tunes from teim and the AFR's have all been spot on.

Here is the graph. The car has a BBR tune, JLT CAI, Magnaflow O/R X-pipe, Magnaflow catback, and the BOSS intake. Run 9 is same setup with stock intake.

It cuts off a little early but looks exactly like everyone else's Boss intake dynos. Loss of 10-20 hp and tq from 3500-5500, dead even from 5500-6500, and huge gains from 6500-7500. If you extrapolate where those lines are going the gains at 7500 are 40+ rwhp. Don't let the loss of midrange scare you. I couldn't notice it but I sure as hell can feel something is up that last thousand RPM before my Raptor lights up (7,500)!

Had a 12.39 and few 12.4's at Firebird last night but today I clicked off a 12.17 and a pair of 12.3's at Speedworld.

Thanks, still about 2 tenths slower than what I wanted, though. I think I'll need better than 2,500 ft DA's to hits 11's as it sits. If you get one get an auto. The auto 5.0's are FLYING!

Actually I do have in-car vids. I'll try to post 'em up this week.

WharfRat, I also have a '11 GT. I put the Boss Manifold on last night and got it dyno'd today. I also have a tune from BBR.

Did you make any dyno pulls above 7000? On my pulls the tune went pretty rich around 7200 - 7300 and the power dropped noticeably. Posted on the LRS forums asking if this was normal.

Your power and torque level off well before the rich spot.
I would rather have it go rich up high. What do you usually shift at?

It's too fat all the whole curve for a N/A car.

Haven't driven it/raced it with the new intake. Before it was done by 7000. Have see others winding it out to 7500+ on different boards.

I agree, it is in on the rich side for a N/A car, but then it goes super rich.

That's a simple tweak that you have to change in the stock tune after it pulls fast 7200 if I remember correctly.

No problems with mine up to 7500 (you can't tell from the printout but it was good to go).

Did you get a BOSS intake specific tune? They sent me a new tune when all I changed was the intake (after I already had a JLT CAI and BBR tune).

Have you called and talked to BBR? They'll fix that for you.

Just came back to post that I emailed BBR to ask about it and they already sent me a new tune.

It is/was a BOSS specific tune.

thanks
