My truck really starts accelerating on the highway with the verter locked at around 30-35% TPS. I never see > 40% unless I got WOT

I love the driver friendly attitude it has putting around town and in traffic, very predictable and easy to drive when you need it to be. of course that's JMO.
I understand what you are saying and that does make the maggie a great bolt on that you use when you want it.

What I find anoying/funny is when i'm kinda getting on it at almost boost, then i give it enough to get into boost.. the tc just slips more and the truck doesn't actually accel any faster. I wish I could experience the radix tq w/ a manual trans.

So why dont you just set your converter to stay locked? Like I said on mine, the only way my converter comes unlocked is if I go WOT.

Turbos are completely different compared to positive displacement blower. The blower is closer to an on/ off switch when compared to a turbo vehicle. With a turbo you just give it a little gas and it will build just enough boost to get you going. Having had both the turbo seems much better on the highway in my opinion.

Thats why I'm buying efilive. I originally had this truck tuned by slowhawk, but I realized I'm jsut way to picky to keep going back to some one. Do you lock through shifts at part throttle?

After experiencing the blower I do wish I had been able to drive a turbo ls truck. I think I would have gone the other way.

Nope, only time my converter locks is in 4th cruising. I dont think it's advisable to lock the converter thru shifts. Im strongly considering a Circle D 4l80e triple disk converter which will allow WOT lock up however.

If you lock through the shifts youll be buying a new input shaft in short order

If you had an aftermarket (higher stall speed) converter you could lower your unlock TPS and when you wanted to pass, it would take less throttle to get you back in the power... It really wouldn't make much difference with the stock converter... Mine locks above 50mph and less than 30% TPS and unlocks with anything over 50%.... It just takes LOTS of tinkering and fine tuning to get it where it works for you.

All in the tune.... as in keep the afr kinda fat at 11:3 or so and keep spark timing low enough to prevent knock?
