I use a pro yank multi disc. Mine is a 3200

 

Ha I planned on boosting more to make up for the lost feel of power. Who knows how long the 65e will last if I keep up at this rate.

So for some say lower stall Rpms, some like higher stall Rpms- it's still the facts that I searched before.
tighter is better for magna Charged.

When truck shifts from 1-2 It would shift at 6350rpm to 4790 rpm with the fuddle- now it's about 4300 with the yank. Where should it be? For the mp122?

What cams and gears ratios? 4wd? 80e or 60e

 

5.3 mp112 at about 11lbs of boost. I have a Yank ss2800, moves out nicely

 

For a PD blower setup we typically use our 258mm or 265mm. With you guys making more and more power we have been leaning to the 265mm more. The 258mm can get a little loose with good low end torque form the PD blower.

Well it's been awhile since I have made this thread- I got about 60 miles on this setup and hate this f******truck now. It feels like a turd, when it shifts I can boost up to 8 psi between half or full throttle and it feels no different in power. Today when it locks converter in 4th at 45 mph if I have it in any boost it has nasty shutter vibrations. Give it a minute reboost to 4-5 psi before I feel it again. 3-4 Clutches going? 2ndgear is hit or miss on glueing you to the seat. Shifting into 3rd feels great. What's the thoughts?

Truck is about to go into storage

 

heads/cam/blown 408 stroker. it's a phoenix 3500, but i'll probably end up swapping to a PI or FTI converter. this is on a lighter setup than you full size truck guys.

 

Not sure on your exact combo but some of it sounds like it might be tune related. Have you re-turned or had it re-tuned since the converter?

I think Roger had this same converter. Maybe he will chime in...

 

I have not had it retuned yet- what would really change? Converter lockup pressure?

 

You hit new cells on the VE table more frequently, and different load ratings at different RPM. Your timing will change because of that. Most often you can get more timing out of a looser converter and make it feel more peppy.

 

Thank you- that is good to know. I currently have Nelson performance tune- I bought efilive but I'm still trying to learn all the details before I switch over and possibly blow my stuff up.

Well that clears some of the power issue up. Now this trans. In 4th gear locked is my concern.
