throttle body

I have decided to sent my TB to get the leak at the shaft repaired. To the folks that have had there TB's bored to 52mm was it benifical? My truck is stock except for a PTE44 turbo and 42 lb. injectors and soon to be alky control. Would the 52mm upgrade help or hurt my performance?

Re: throttle body

who is doing it? I had mine done and the quality of the work was awesome. If you're widening the passages then you're going to let more air in so it can't hurt - you'll maybe not notice anything exceptional but it will be of small benefit.

The real benefit as I understand the work is that the shaft won't develop play so your idle issues won't be due to that if you ever get any.

mine was by matt blum (see the pics in my sig) and he did a great job.

If the vacuum leak is repaired and it runs any better I be very happy. For the cost of the upgrade over the cost of just having the vacuum leak repaired. It was hard to pass up.

Re: throttle body

i dont really think even that little leak that they all have makes any difference really.

Really, I am no expert by any means. But when I tried the bicycle tube test. Pressure held for about 0 seconds. The only place that I could verify air was leaking at was the TB shaft and it like felt like several psi. was coming out. I didn't think it would hurt anything if I corrected that.

My thoughts exactly.
