turbochevy

A couple weeks ago i was driving my 72 montecarlo twin turbo to my new apartment. I just drove this thing 45 miles with a CRAPPY tune, just enough so the car would run. Well i just got off the 15 freeway and i was headed to my pad. I look in my mirror and see a GTO in the distance. I was about half mile away from my house and i see this yellow gto coming up quiwk, so i was like what the hell. We pull up to light , when it turns green we take off normally and i hear him wood it, so i do the same. Well with this crap tune my car stumbles and pops.The gto had like 2-3 cars on me, well then here comes the boost. I caught him really quik. I went by him him in second hazing the tires and had pulled 2 cars on him. We get to the next light and went from a 25-30 mph roll. Lets just say i never saw the back of his car again. We get to the next light and he asked me if i had a big block, i said no just a little 350.
