Re: 1st test with datamaster

these truck even with a perfect stock tune up will idle kind of crappy,also stock dist will make them idle like crap as they can short out inside.

Also hw accurate is the dyno and 1/4 #s on datamaster? It was saying I ran a 13.7@99 and made like 250hp and 430ft/lbs@ 2900rpm The 1/4 sounds about right with the way it is running but that tq # seems alittle suspect.

The 1/4 mile calculator is real close. I think the dyno is silly. The numbers it gave you look about accurate for a stock truck. That tq# is actually not real far off. Thats what makes these things such launch qweens.

Re: 1st test with datamaster

exactly how my idle is. i've done every suggestion on here that i have found so i bought datamaster to see if someone on here can figure it out also. just need to find time to log in some runs.

I remember a while back ed hess had this problem and a slight hesitation from idle to throttle and after tons of parts and tons of time he ended up yanking the motor to go big (this was bakc when he was running 12s or 11s I believe) and what he found was that the stock lower intake gasket was bad and basically creating a small vacuum leak. Don W also found this to be the route to a hesitation issue he was having as well, not sure about erratic idle though. another thing to check out is what your afr is at idle, try to maybe richen it slightly to see if idle improves? but remember these trucks came from the factory which bad idle due to the tune with emssions in mind.
