your LS6 intake is fine or you need to go to a single plane carb intake.
they arent stupid, its a solid 15-20hp gain. Its just an expensive mod and usually your money can be better spent elsewhere, unless youve run out of other mods

Well I think going carb is a stupid idea . But you will see 10-15 form a LS6 to a fast . I have a buddy that picked up 20rwhp form a ls6 .

I thing the people complaining about the price of the intake are just on a tight budget, but not many mods give that much power .

Wow people gain 15whp going from the LS6 intake manifold to the Fast 90 with 90TB?

That's pretty impressive and definitly seems worth the price difference to me if indeed true...

How does the Fast 90/90 affect driveability? Response? Top end? Low end? I've read a few post of people complaining that they're 90/90 setup doesn't drive well. I have no idea what they mean.

Just reading the description of the Fast 90 with 90TB combo, it doesn't say anything about a loss of driveability in terms of daily driving. I'd assume the only issue would come if someone freaked out when trying to tune and the car didn't run right with the larger throttle body. To each his own.

According to TSP, upgrading the LS6 motor with a 90/90 gets 15hp. Sounds very worth it to me the more I read about it. Even with the stock cam!

Before I did my heads and cam I put the fast 90/90 on, and I definetly felt the difference but, being that I had a bone stock motor with full exhaust and no backpressure and stock gearing It made the car alot slower down low. But when I changed all that it didnt matter I have power all the way through the RPM range.

I have no drivabilty issues with mine . But being its a two piece intake they do have a problem with them getting vacume leaks they may be talking about that . If not It may be in the tune

The 90/90 works better with a h/c I would put one on a bolt on car .

FWIW, I talked to TSP yesterday about this same thing - the MS3 and Stage 2.5 5.3 combo. The guy I talked to said you DO NOT have to flycut with those heads. Bigger valves, yes you flycut. But not with those heads and the MS3. He told me it was the same thing he had in his car.
