I need to know what to upgrade next. I just purchased SSRA, lid and bellows and I want to upgrade one more thing. Your input needed all-knowing gods of LS1 modding!!!

A ported throttle body will definitely give you a better gain than a MAF.

If you'll do some quick research, you'll find that a lot of people have problems with aftermarket MAF sensors. Most tuners won't even touch them...they'll ask you to put your stocker back in. Just do some looking around, and you'll find out why...I don't really feel like going into the technical parts here.

I'd do the ported TB if I were you...and if you really want to do something special, get some tuning software, learn how to use it, and do a speed density tune that will allow you to tune out the MAF sensor altogether. That way, you can get rid of the whole thing and just run a silocone hose from your lid to the TB. Not for the faint of heart...

changed out MAF's will only benefif you IMHO when you reach a HP point where the stock MAF becomes a major restriction. then get a delphi z06 MAF where there are known tables for it, and it can be tuned for.

i say get a ported tb and call it a day. shaner can hook you up man. quality stuff at a reasonable cost.

Upgrade to a ported TB. Aftermarket MAF's (like said above) only provide headaches. I've heard of people actually losing hp from the Granatelli MAF.

NEVER change your MAF

Definately the TB, aftermarket MAF is a questionable Mod as stated above.

Your car being an automatic, your next mod should be a higher stall converter.

I agree with the ubove statements on the maf. I was a few hundred miles from home at speed inc for my dyno tune and got lucky they could tune my slp85mm because if they couldnt i was going to have to buy a brand new one from them.

I am so glad that this forum exists. Thanks for all the help everyone!!! Can anyone explain to me briefly where my bottleneck is going to be. I know it is inevitable. I will reach a point when I have more air coming in that can go out. What will be the best thing to upgrade next? LT Headers? High-flow cats? This is not a race track car (for now) so I need emissions unfortunately, but I have the loudmouth to free up the exhaust. Any thoughts???

Thanks,
Kyle

Lts would be a good investment. You have a 01 so you got ls6 intake covered. Check alot of people's sig's many are running lts with catted ys making great power. good luck

As long as you stay the hell away from SLP lt's, you'll be good to go. I see in your original post you're lookin at Kooks headers, which is good. SLP has some serious fitment/clearance issues goin on. Kooks is where its at

Or Hooker's.

get the TB as for headers..man, thats a whole nother debate but LT's+ory+loudmouth= nasty!!! rasp

I say MAF if you have HPTuners to tune for it.

I had the LM on my car for a while, but when I bought my Kooks and catted y, I also bought a GMMG and have no regrets spending the extra money. A tune would probably net you some extra power as well. A new rear end also gains importance once you get some traction. With an A4 though, it's hit or miss in regards to breaking, but nonetheless it is a weak link.

I would also add "and some serious knowledge of how to use it." Altering a MAF table might be a bit much for the average owner...
