what's the size of the stock tb?

 

I think it's 68.5 mm but tapered

 

well I bit the bullet and ordered the 68.5 tb and soon i will order the super chips... and thankfully I have access to a dyno at school. so perhaps I may be able to sweet talk my professor into letting me do a few pulls on it.

 

Do before and after, or else you won't know what the add-ons are doing for you!

 

any rough ballpark estimates of what I should see for numbers?

 

parts came in today. the tow tune makes a huge difference! hoping to play with other tunes soon. gonna be installing the tb tomorrow sometime.

 

Told ya, told ya! I love me some Tow Tune! I think its the best all around tune for our trucks. I always felt I had to beat the truck to make it feel peppy with the 91 Octane. The 87 was an improvement over stock but not like the other two. The Economy Tune/Gas Saver, etc was so sluggish and retarded

 

I am now looking into an efan. any good suggestions about what to choose?

 

VOLUMES written on that elsewhere in the forum - search and learn.

The one I'm considering (have most of the parts) is the Taurus (pre-95) two speed fan, Volvo relay, BMW two-temp switch set-up. Simple operation - too hot, switch on, big fat relays to switch the power. And word is that it cools well.

Cheers!

 

Did you actually get a TB for the 2008? I keep looking and I can't find one
