Well i spent some time working on the Turbo Sierra pickup today (Badcutt / Seth)...
After working through a street tune getting driveabilty all squared away aside from a pesky idle issue due to the MAF's location more or less.
Pretty much went though and fixed all the eroneous tune glitches like proper injector scaling so the thing recieves delivered fuel accurately at all times.
The fun to drive factor that was able to be squeezed from the thing is pretty awesome! It spools effortlessly now when you demand it in part throttle where it was a slug before. Starts to roast the hides at 50% throttle and 5 psi now.
We threw it on the dyno and began to plug at away at the wide open tune, it was UBER fat (10.2 AFR) through out the whole powerband, now that i found the smoking gun for the reason it wouldnt pull over 4800 rpm;s, which was another torque managment function that is only seen in extreme torque situations. Took care of that and she zings right to 6K now with more than enough fuel. (Not the fuel systems short comings as someone tried to lead people to think...) So a couple pulls later the AFR came around into the low-mid 11's with about 17 degrees of timing were set and all the while seeing 10-11 PSI max boost. We had some issues with the dyno not producing the numbers correctly due to the tach read was intermittent. But it was just shy of 500 to the wheels and 520 tq on 10 PSI and now spins to 6K.
On the street the thing is pretty bat shit crazy... Very little lag time and when the hair dryer hits full song and send all 4 tires into a chatter from 40 and sets you back to watch the speedo rocket twoard 100 mph, that left me gigling like a little school girl afterwards.
So its safe to say its a pretty bad ass, FUNCTIONAL setup now.
Glad i can help sort the thing out, nothing is cooler than seeing the owner aglo with happiness that they are finally seeing full potential of their money spent.
