I will start of by saying i went to the dyno on my street tune. my AEM wideband read 11.5 in boost like i had tuned it for. But the dyno's wideband read 14.5 i made 190hp 195 tq at 8psi. I added fuel got the dynos wideband to 11.5 made 245 hp and 285 tq. So i know it was my wideband. I then turned up the boost to 12psi AEM wideband read 10.5 to 10.0 dyno read 13.5 to 13. I got the afr where want them made 298 hp 333tq at 12psi.
This is a f22 they seem to make more tq then hp

I am thinking of getting lc-1 or plx

 

Innovate makes the most accurate widebands for the $$$

 

If you are going to buy a new wideband, I'd definetely suggest the Innovate as above. However, have you tried re-calibrating your current wideband??

 

AEM units do not require re-calibrating once you do the first free air calibration.

Innovative is a pain in the *** IMO.

I've been through 5 widebands and the PLX has been my favorite considering it has given me zero problems even having to take it in and out of every car i tune and the wiring took 2 minutes.

 

Toss up between the Innovate LC-1 and the NGK Powerdex AFX. I have never had any issues with any of my Innovate products. I prefer using the Innovate due to it's adaptability and data reliability. The AFX is spot on, even though it's not adjustable (0-5v output), for datalogging it's very accurate.

 

I got a lc-1 and love it. datelogging is dead on
