LS6 intake manifold upgrade will help too.

What do you mean by custom tune ?

Car ran great; however most of the gains I noticed were from the built trans/gear I had in it.

You see I have a brand new trans in mine and new heads, but idk where to start??

One could add more timing, adjust power enrichment settings and WOT fueling to help gain some power back and throttle feel. Transmission shift adjustments and knock retard changes ( they are pretty sensative from the factory). You'd want to be running 91+ fuel if did something like this to gain the most power possible and prevent spark knock.


Past that you'd need to install an aftermarket camshaft, maybe some headers and switch to E85 to get the most out of the engine NA.

Thank you sir

you could put a cartuning turbo kit on it and make 500 hp at the wheels. they come complete with everything you need and cost a minor 5500 dollars

You're not going to keep 500~ horse in a stock trans for very long at all.

And anyone that tells you that you can, is a damn liar.

Yeah I'm aware of the trans on these cars ... But I'm saying the engine it self has 145k on it , will it do anything if I put a turbo kit in it cause it is high mileage, trans I'm aware of though.

The AFM/DoD cam and lifters won't like a lot of horsepower and are prone to failure even if you turn it off in the tune. The injectors are tiny and won't support boost at all, same with the fuel pump.

Aaahhh I see that makes sense... Hhhhmmm some small upgrades like the exhaust , and intake and tune would be enough your saying..

the intake manifold on the LS4 is pretty restrictive and people swap to an LS1/2/6 or 5.3 truck manifolds. the LS6 manifold seems to flow the best and some people claim they get an additional 20 hp just from that swap. Overkill claims his tune will get about 10-15 hp, but I think you have to run 91 octane.

See I go from mid grade too premium, but I saw Overkill's tune ... And a ls6 intake seems to do the trick for some people I heard ..

for more power I suggest you get a 2017 ZL1 Camaro lol
