have you guys ever heard of this company? If so any thoughts?

Thank you

 

so i ended up getting this

https://d3performance.net/index.php/...ormance-tuner/

I have catless headers and i keep getting this 02 sensor issues from my midpipes and ive tried 2 different sensors.

They said they can send me a tune to delete that out, ill keep you guys posted

 

Haven't heard of them before, sound like some stuff that would break your car down imo
I used D3 and they're reputable and reliable.
Might try out OV

 

Agreed. A) Prices are too good to be true and B) 9 times out of 10, something that just plugs into your OBD-II port is going to do nothing.

 

glad to hear you’ve heard of d3 . Thanks for the reply

 

Whats OV? do you have a link?

The site said TCU can be tuned so im interested in buying the software and have my tuner look at it

 

OV/VF is promising but pretty sure can't fix his code problem, I know they can't with F models.

 

what midpipe are you running?
Did u try to clear code or does it pop back up

 

oh so everyone is having this issues with this code issue ? I thought it was something my mechanic did or bad sensors I got

 

PPE , and yes tried resetting the ecu and nothing works

 

Is your code P0420 or P0430? If so, those codes are due to you not having cats. The codes can't be fixed unless you have cats or tune out the codes. OV/VF has not allowed that option with certain models, including F cars. You need a tuner who can turn off those codes. Make sure they can before you get a tune.

 

yes both of those codes , and I verified with D3 they could send me a tune that can get rid of this. Hope it works

 

got the d3 tuner today, it came with 3 pre programmed tunes. i called dennis at d3 and they are gonna send me the tune that i picked and also remove the 2 codes for my catless headers hopefully by tomorrow

can definetly feel the difference in the tune!

 

Did you consider RR Racing tune? Curious as why you went with D3 vs them.
