So, after sitting in my garage attic for a year, I finally installed the headers last night while care was in my garage on jack stands. I'm probably going to do the tune through Diablow Lew but assuming will have to wait until spring when I can actually drive the car and log the info.

I'm looking for other ideas for anything that I can/should do this winter before a tune that may help. Any ideas for upgrades that are worth the money vs. gain?

Not looking to spend thousands..... but maybe I'm already about as far as i can go for now .

current mods:
OBX/Maximizer long tube headers w/ catted x-pipe
Airaid CAI
Corsa sport axel back
Diablo sport trinity tuner

I will more than likely be initiating a tune via Diablo Lew this spring to bring it all together.

anyone have a similar set up that can give me an idea on HP gained from stock?

what would next step(s) be?

a ported Fast 102 would be a good next step.

I've been looking at those actually

I would deff not go to a larger T Body We were trained at EFILIVE to only use a larger T Body IF
1 you increase your cubc inches from stock
2 Major mods --Huge cam better flowing heads\\
3 You typically run your car above 5500 RPM's ALL the time
It's like putting too big a carb on an old sch engine--You will lose bottom end HP/TQ as well as mid range but add only minimal HP at WOT
I'm not sure you can properly tune LT headers with the Diablo tuner
THE best mod peeiod you can make on any automatic car is to add a stall converter
This wakes up even the laziest of cars I would recc a 3000 Stall for your car

hmmmm16417

Haven't even thought about a stall converter yet..... may look into that .

I saw throughout the forum that using the trinity tuner I could send logs and have it custom tuned by Diablew ? that isn't very good?

Yes it is good as a lat resort---However you will end up doing many emails back and forth and trying to explain whats going on in your car----Best is to have a local tuner work on your tune and they will actually DRIVE your car and realize all it's tuning deficienies----Much easy to tune an engine when you can drive it-----A mail order tune is just "their best guess:"of what needs to be changed--

If car is an LS2, I would venture to say that a ported Fast102 is the best bang for the buck improvement, pre tune. If not wanting to spend quite that much, get your LS2 stock intake manifold radically ported.

I'll have to look around. Not sure there is a reputable tuner in my area. I know of a couple that do motorcycles, but not sure about cars.

Yes, it's an LS2. I've been looking at the fast 102, but still debating. it's starting to seem like one mod leads to another essential mod. hahahaha

As already said, A fast intake and ported TB will be a great addition for HP and throttle response. Then your looking at installing a cam next if you wanted to stay NA and go farther than bolt ons.

You'd be amazed what a difference a throttle response controller will make. Chuck Cow can program your cars computer with similar results. Reallt cheap mod, huge difference.

It wakes the car up. Makes it snappier, way better. Look at Vittesse, they make it adjustable. You can find them used here sometimes for $125 or so. No brainer.

Thank you very much!

YES, the CoW BOOSTER! is amazing and can be set up any way you like.

Throttle bodies and fast manifolds are virtually worthless without displacement, compression, or big camshaft mods. The perceived improvement comes

comes from a slightly larger throttle body but you can get much more bang for your buck with a $199. CoW BOOSTER!

Thanks again!

With a ported Fast 102 and OBX catted LTH's my car picked up between 55 and 65RWHP NA depending on DA and dyno car was on with no increase in compression,displacement or large camshaft

tblu92

Sorry I can't beleive this maybe on a Silverado that is not well tuned however a Corvette is already well tuned from the factory and the mods you say you made a 102 Fast intake and LT headers do not equate to 65 RWHP
The Fats intake also only makes best power gians at WOT like above 5500 RPM 's and maybe even being generous you would see on a STOCK INTERNAL engine at best 15 RWHP --Then LT headers only after being tuned may add another 25 -30 RWHP So combined this is only about 40 45 RWHP --even after a tune----As when adding the 102 and LT;s your HP and TQ may be even LESS than before until you have it tuned---These mods are worhtless without re tuning and even then no where near 65 RWHP !!

A ported fast 102 may be the absolute best mod for an LS2. The difference is throughout the entire power band, not just up top. A good port job can add 7-10 rwhp over a non ported one.
