Want tuner for 4.6

Hey Guys, can anyone suggest a tuner for the Tundra with a 4.6L engine?

Thanks in advance.

 

Welcome from Northeast Connecticut. Someone will ring in on a tuner

 

Only thing available for a 4.6 is Hypertech. But if your truck is 14+ it’ll likely throw a check engine light.

To optimize a stock truck:

Stock air box mod
Throttle body coolant bypass
Bamufflers catback

 

dirty deeds can you maybe explain what the coolant by pass does. I've seen a lot of back and forth but no exact answer.

 

Can someone explain in what consists the Stock air box mod?

Thanks.

 

By lowering intake temps you reduce pre ignition

Our ecu constantly pushes for more timing. It’ll add a degree here degree there little by little until it hears preignition, then pull a block of 4 degrees!!

Then later try to add it back. And the cycle continues.

By suppressing pre ignition by lowering intake temps you get to keep more of the timing your ecu is trying to give you.

To sum it up, initially there is zero difference. But in the long run there is slightly better performance. Being a totally free mod what do ya have to lose??

 

im putting on the trd intake this weekend! what does the tuner do in regards to performance? is the trd intake worth putting on? my issues is I fill like I've lost some low end pull. I want to make sure I put on the right stuff for more bang for the buck.

 

what is the best tuner hypertech has 2 but im not sure which one to go with
they have one that plugs into the truck under the hood looks like plug and play
the other one looks like it pugs in and you can adjust the performance

 

I have hypertech and pedal Optimizer very noticeable difference

 

search youtube for Tundra SABM, it adds an additional coduit for air flow to the box.

 

Try it without the pedal module. Just the Underwood module. It really wakes up

 

Underwood module????

 

Anybody know anything about this?????
