Re: I absolutly cant beleive it!!!
Well, I'm just finishing up my first tank with GTA.<br />I'm running it in a 1987 GMC 3/4 ton conversion van, 3 speed auto trans, throttle body on a 305 v8 5L, supposedly producing 158 hp, 149,000 miles.<br />This vehicle has always been a dog, you could always feel a shudder and a slight knock under "attempted" heavy accelleration. Had it since new and no tune-ups ever seemed to help.<br /><br />It definitely has smoothed out the motor some, and it accerrates smoother and quicker (don't ask how I know this).<br /><br />Used to have to push the petal to the floor and wait 1 second for it to shift into passing gear, and then it would generally just produce more rpm but not much more power.<br />Now, push it half to 3/4 down and it shifts instantly and provides a welcome head buck and accelleration!!!.<br /><br />No mileage check to report, yet.<br />First towing to be done today.
