im in the middle of the ultimate tbi mods and i was just wondering how much of a difference will the mods make? will it be noticable? does anyone have pictures of the ridges removed?

 

its noticable

go to my site - see the sig.

click photos. tbi related.

 

NJSpeeder would be the best guy for this question. PM him if you really want the dirt, but I believe he has said before (tested) that the Ultimate TBI mods are good for .1 or .2 in the 1/4, which aint bad for FREE!

 

Yeah i could tell a difference and im pretty sure my customers could too.

 

do the ultimate TBI mods risk smog failure? The state of CA is pretty crazy about their emissions standards. thanks a lot.

 

i can tell you one thing i gained about 1-1.25 mph in my trap speed an that was at last years f body nats in the heat. I mean i didnt get a better et but thats in part because of the heat and my best of 14.7 was done in the fall. So to answer your question its definetly worth it (Couple hours of labor for a mph at the track)

 

i didnt fail emmssions and it really only takes les than 1 hour if you have the right tools thats how long it took me.
