Re: 77 c10 5.3ls turbo

Haven't made any changes and haven't put as many miles on it as expected. But it is running very well, a pleasure to drive and it rips. Drove maybe 250 miles. Picked up some other cars this spring that diverted my attention. One of them being an 90 SS 454 .

At 13lbs and tuner says I will need a speed density to go even a 1/2lb more. Haven't had it on the dyno. Hope to do so in the next month or 2. Tuner is really busy and Im not in a hurry. Only thing I still need to trouble shoot is the VSS, it isnt working so it sometimes dies idle..
