High Flow Cats and Tune

Ok I'm currently running the Cold Air Inductions CAI and the SLP Loudmouth II axle back. I also have the apex scoop and WWF bottle relocation kit I still need to install. I was looking at getting the solo performance high flow cats and a trifecta tune. Are high flow cats worth it? What kind of gains am I looking at?? Also debating the VMAX TB?

From what I've read on here The Vmax ported tb Doesnt produce massive gains maybe only 5 rwhp and about the same tq. However it seems to help the feeling of the car off the line and is supposed to help that seat of the pants feel and throttle response and would definitely compliment your intake system. Also from what I've read the solo HFC are good for a NA build but people have had trouble with them(ie melting) if your considering going Forced induction. Just giving you a heads up. But the seem like the most quality HFC so far but they'll be fine if your staying NA. Id say conservatively they'd may give you a gain of 8 or so. With all your mods i'd guess your gains if you also included the Vmax tb with your trifecta tune, id say maybe a 20-30 gain. what does everyone else think?

yeah the V8 is a little more mod friendly then the v6 but you should still notice some gains and wether you gain 20 hp or 10 thats still more than you had before! Suspension mods as well as lighter wheels will also help your car feel more athletic rotational mass is always the enemy. Even if you only go to lighter wheels and lose 5 lbs from each corner thats 20 lbs of rotational mass gone and itll feel more like 40 lbs of static(stationary) mass because your engine has to do less work to turn the lighter wheels. Lower and stiffer springs or coilovers will improve the feeling as well. And if you feel the bolt ons arent helping much the 3.91 gear available from LPE or GM will really wake the v6 up off the line (if you have a manual you can use the 3.91 gears if you have an auto you'd have to swap the rear end from a camaro ss to use anything above a 3.55 however even a 3.55 is a big improvement. Anyway sorry for rambling!

It's an auto. Is that 5hp picked up from the TB worth the $150? Definitely going with the HFC and tune. Sounds like the HFC are a must for this engine. I'm not planning on going forced induction. Just trying to squeeze more power out of this LFX. Thanks for the input, I don't mind the rambling haha
So should I stick with trifecta for a tune with my set up or should I go somewhere else?

My RS had an Injen CAI, Loudmouth exhaust, VMax ported TB, and a trifecta tune. This really opened the car up. I did not get to the cats before I wrecked it :( so I could not say, although I just went catless and LTH on my ZL1 and made a hell of a difference. I would say go for it.

I had trifecta, but switched to a tune with hp tuners and never looked back. Personally I would not get a Trifecta tune again now that hp tuners supports the lfx. Alot of guys went Trifecta initially because there wasn't another tune or tuning suite out at the time...

Hp tuners is a tuning suite. Many speed shops use it to tune. Tune price will depend on the tuner you take it to. Personally, I would skip the ghost cam tune.

Ok I gotcha. I guess I need to start looking for a shop near by that uses them then. Why would you skip on the ghost cam?

The ghost cam gets its loping idle from misfiring the **** out of the engine.

And no I haven't tuned yet. Big power gain with the cats too.

I would skip the ghost cam tune because 1. No performance gain. 2. I don't think the Ghost cam tune is good for the engine.

I usually just look at the LLT forum but accidentally clicked on LFX today and had to reply-

Loved my Solo HFC's! They are a perfect match to your well modded LFX and I strongly recommend them. You won't disappointed by the sound!

I see you've got some experience with Apex Speed- http://www.camaro5.com/forums/showthread.php?t=335942

Enjoy!

Has anyone running the Solo High flow cats run in to problems with emission testing? I know they are not CARB certified. I have to pass the emission tests for Travis county Texas and want to make sure this won't be a problem.
