Cold starts are as expected with fuel injection.Rev's high initially on startup but settles down to about 1000rpm while warming then gradually idles down to whatever you've set your min. idle at.(approx. 600-750rpm).

I noticed a 50 mile increase in my milage.I have a stock 21-22 gallon tank and got approx 50 miles extra to my tankfull.That was highway and with my 700R4 working as it should.

Low end tourque is awesome.No stumble off the line at all.
It does peak out,as far as power goes,around the 5000-5500 rpm mark but that's what it was designed to do.
Stock TPI is not meant to be used in a high reving application.

Here's my TPI in my 71 Blazer.
