I saw zero E.T. gains, and my trap speed stayed the same, (LS1 intake & no tuning) when my Hooker/Jet Hot LT's w/ORY were fiirst installed, After a trip to my local LS1 edit tuner, then I saw an improved E.T. at the track by .30 and 1.5 mph trap speed. Looking back at it, I believe you really need to do a cam at the same time to realize bigger gains, ( H/C even better.) Mine was running a 3" cutout before the header install. (A4 trans)
If the tuning would have been on a dyno w/ wide band, I probably would have picked up more. I was waiting until I got an LS6 intake on before dyno tuning, but that never happened. Started my 422 Super Stroker project instead. The 422 is being installed and will be fired up this weekend for the tirst time. (I finally went with an LS6 intake) From what I kept hearing about the LSX, I held off on buying one of them until they prove themselves to be worth the money.

Will I gain about .2 tenths with 5 mph more on my E.T. in the 1/4. My old E.T. on the 1/4 on motor was a 13.566 in 102 mph. My new E.T. on motor in the 1/4 with the LT/ORY improved to 13.390 at 107mph with some spinning on my stock A4. No Tuning. Just wanted to know if this were more or less the kind of gains on the E.T. 1/4 expected when installing Hooker LT and ORY. Next Mods will be ASP Crank Pulley, LS6 Cam and Vavle Springs, and the performance LS1 intake. Hopefully, I can hit a high 12 with this mods. Thanks for the info!
