If I remember correctly Detroit diesel, introduce 6.2 1982 143hp 257 tq I though it was a diesel,but guess I am wrong, either way it was down on power.
I am also interested, so far 114 is the most and 102 is the least mph before computer shut it down, However, the 2019-20 has the highest mph limiter from factory. That is of any gm production truck, Keep us posted on where your's fall in at.Thank's
Wow interesting all the one around I know of with out tune to move limiter out they was 98,With tune like my ss it will run past factory setting,With a tune that is.Suprise you don't throw your drive line out.
