I would suggest them not as an increase in mpg but piece of mind. There's no reason the inserts alone helped the mileage out aside from better clamping being able to take place.
When I swapped turbos I put a set in my truck and come to find out when I pulled the spyder apart I have a massive boost leak at the orange boot. Someone had taken it off before and didn't realign it right. I was only getting 15 pounds of boost in all my tunes.... You never know what you have to fix until your in it already... Worked out great for me

I did some on my rig, but can't tell the difference cause I NEED up pipes. so I am saving.
and those T-clamps sure are sweet. but as I i was clamping them down I never seem to get "tight". was afraid of cutting into the boots if I went any tighter.
once I get the up pipes installed I hope to gain better MPG's and power. cause gauges are next.

The stick/38R install was a disaster, plain and simple. I barely got Stinky running to get home. Leaving the failed IPR out of it, almost every clamp related to boost gave me fits because half the clamps stripped out, the IC tubes were out of round, I didn't clean the boot mating surfaces properly, and we forgot to tighten one clamp. No pop from the loose clamp - our work was so schlocky that it was just a hissy fit. I put in the inserts the first time, but the intake plenums leaked... so the inserts were gifted to 2000ca250 for helping me with the truck. I bought the billet plenums with O-ring seals because:
- They are much stronger than stock, this is a true upgrade.
- I don't have to worry if I got the mating surface free from oil.
- I'm not waiting for sealant to dry before I know if it's fixed.
- If I do have a leak, a redo doesn't destroy my previous work.
Remember - the clamps with the springs all go on the hot side of the IC.

IIRC there is a torque spec for the spring clamps, is there a torque spec for the t bolts with no springs?

happpened to me as well, the other day, tooling around. First, i cant comment on mpg gain, because it was one of the first things i installed in my truck, but man, sure bets clamping down on tin metal.
As for the t-clamps, i blasted 4 of them. They seem to be a 2-3 time install/removal item, and thats it. Give that little extra turn and bam, threads stripped. Also, i got the 3in t-clamps, and with the tightening, they looked bottomed out. I'm in the hunt for the spring t-clamps, them factory ones are still goin strong...

Using my method with the thick CAC boots, they have survived about 5 removals. The clamps on the IC tubes have endured about 20 removals or more. If I keep this up, I should look into adapting my clamps with latch handles.
The spring T-Bolt clamps (medium duty) require 50 in/lb of torque on the nut (now I need to calibrate my cordless drill). For your reading pleasure:
