SCT Tune Issues
I had some issues with two of the three tunes: the economy, Ran nice and smooth, but when climbing a steep hill at hwy speeds in overdrive (no load or tralier), it started pulsing about every 2 seconds, power, no power, as if it wasnt getting enough fuel, and I know its not fuel filters, or a weak fuel regulator spring (been replaced). I believe the original purchaser of the SCT and tunes had the same issue. I'm sure this tune will not work for me since I tow my horse trailer 75% of the time.
This cold mornin, I went to the tow tune, and started the truck after loading, and it seemed to be over fueling, way too much blue smoke, and it wasnt hitting on all cylinders. I didnt try this tune more than 3 minutes.
Then went to the street tune, Lots of pickup, havent noticed any issues, but I did noticed the EGT make it to 1000* when flooring the pedal. I'm suspecting this is normal.
I wonder what could be wrong with the first two tunes, The original owner had the same strategy as mine, Have any Ideas?
