You send them to someone that knows what they are doing....
I'll vouch for that. After struggling with brand x beginning of last year, I switched to another tuner, and never had them back off the engine. Looking at them side by side, it's clear there are very different theories out there on how to set up for fuel.
Ha good one kelly..Thats a very smart idea. Only I dont have another three hundred to spend..Or I might send mine off or buy the ones from oregon. Talked to seros and cleared stuff up for me. Ill call Randy and see what Odem told him. Oh and sleepy is right. I got some from brand X them got some from Brand S and was a total diff story. Great success with the seros stuff obviously has not failed me yet and have not replaced a single piece since 2006. Thanks GUYS
