Yes I had it tuned but all that needed to be done was to add alittle fuel the tune for the cam and heads was done before the intake and T/B swap. The spec's on the cam are 221/221 559/559 114 lsa

Personally, I don't think the extra 5, maybe 10 horsepower, depending on cam/heads, is worth the extra money. Almost $1300 on intake. I can spend little less than $500 and get slightly less power. Unless it is a bigger displacement motor, it is not worth the money. If you plan on going bigger, it is worth it.

For 5 to 10 HP I would agree but I gained 27 rwhp and I didn't spend $1300 either. Also power throughout the curve was increased and the car just responds alot better at any rpm. You also would spend about the same $$ for a quality set of headers and get about the same gains so if I would do it for headers why not intake.

My gains were over the LS6 but I agree there isn't anything cheap for the LS1's.

I am just wondering what kind of gains you might have seen with a 78mm
Has anyone with a 346 tried both 78mm then 90mm intakes that could show a graph with the gains

I've just been told that the lsx intake just isn't worth the money by several shops, and let me get this straight. You had a heads and cam car with an ls6 intake. Then you saw a 27 rwhp gain on an lsx. Is that correct?

Thats correct, I went from 388 rwhp to 415 rwhp and that was on a Mustang dyno. Torque went from 373 rwtq to 386 rwtq also. Jay at Absolute Speed is the one who talked me into it he said with the heads on mine car with the B1 cam I should see about a 25 rwhp gain and he was right. He did a flow test on the LSX 90mm and said it flowed alot better than the LS6 intake.
