What's next

Ok so here is where we are is there anything else I can do bolt on wise for small gains she dyno'ed with current mods 378 at the tires seems a little low I went with 1"7/8 headers no cats and stock exhaust out the back cause I was told no real gains from axle back.

2014 2SS Camaro
L99 , CAI, 3.91 Gears , Vmax TB, Stainless 1"7/8 headers and Lethal dyno tune.Best 1/4 mile time 12.37 @ 115mph.

Has anyone dyno'ed with cutouts open was wondering if I would see some gain or just noise thinking a convertor might be the only thing left and I am just not ready yet to split the motor and tranny yet.

That's what I Dynoed at with similar mods and tune. I hope to add 3.91 gears like youve done eventually.
My best is 12.89 at 111 mph.

With CAI , , ported TB ,3.91 gears, and hand held tuner she went 12.81
you will love the feel from gears absolutely one of the best mods so far.

I know a guy in town has exactly the same mods as my wife's car w/the exception of cutouts and he's told a few people he dyno'ed 390hp THAT'S GREAT NUMBERS IF IT'S TRUE i know it can very a little from car to car they won't dyno the same #'s but hell 12hp more w/basically identical cars has me wondering 5-6 maybe not double digits but looking at the 1/4 mile times on the fast list seems we are a little slower then most so who knows just checking.

Get a Rhino (GPX) Ported Manifold and swap out your TB to one of Bo White's imop. Also you could look at doing an Underdrive Pulley.

Well I got the VMAX TB , will look at intake's but didn't think they were worth the money that on stock internal motor I wouldn't see any gains.

3:91 gears will be the biggest bang for your buck. I bought a used 1LE Diff for $1000.00 and installed it myself then sold my 3:45 Diff for $650.00.

VMax throttle body is cheap fun as well. I put one on my car and noticed a big difference... Not in power but in throttle response. So much so, that I had to adjust my shifting. Meaning, my clutch to gas peddle ratio changed. You know, drive stick for 15 years then jump in a friends car and feel like a newbie.

Scoop and washer tank relocation kit will add a few HP. Torque converter would be my next step.

scoop and washer tank is used in conjunction with CAI system ,may look at cutouts as well both might be good for 5 hp gain. I have and love my 3.91 gears and agree totally the Vmax TB was a great mod as well.

Scoop and WW tank relocate wont really show much gains on the dyno, as they rely on moving air to really do their job.

You could also look into the Vitesse Throttle Controller.
No actual HP gain, but opens the throttle blade faster= better acceleration
