What to do... Boost or tranny stuff or chip?

[robertk]

Well I have a 2001 Ex with 107K 2wd and full 4" exh and int kit. Other wise all stock.

I have a new large 6.0 trans cooler and pyro and trans temp gauges and regeared the 3.73's to 4.10 since it has a 35" tire on it now, back to stock final drive.

I have gotten readings of only 15-16max PSI under full boost and just dont think its running to its full stock potential even. It towed my 7000lbs buggy on a trailer with no issues but just seemed a but under powered.

I was thinking of a banks wastegate and setting it to 19-20psi and maybe a chip.

Would I be better off doing a trans mod (banks controller or solinoid looking piston mod or ?) and then doing say the wastegate?

I am not looking to get alot of anything out of it. Just more then it has now and reliably. SO I am leanign towards the banks trans controller and the wastegate.

any opinions, thoughts, recommendations?

thanks

I don't think the wastegate is going to get you where you want. I would suggest getting a valvebody for the tranny.. .then get a chip...that chip will do more then the Banks transcommand can do for you.

Once you do this I wouldn't even bother regearing it to 4.10's for 35's. Your truck will come alive with the chip and still will be reliable. You will lose some fuel mileage going to the 4.10's if you do alot of highway driving...

Thank you for the post.

So since I am too scared of doing a valve body and dont trust one local shop... Does the DP chip/tuner do any trans controlling/helping?

it is as I type mid gear change. so it is done basically. I do alot more around town then highway and since its a EX and weighs more then my house, I figure gearings will pay for its self in around town MPG quickly. For long hauls the speed limit here in cali is 55 and so at 60-65 I will still be just under 2000rpms, or so the calculator I used, says so. That should still be decent MPG I hope?

As for the wastegate. I am just hoping to gain a few PSI and at only like 150$ and about a hour of work, I figured it would be a worth while investment?

16-17psi boost is about all you'll see out of a stock truck. Changing the wastegate won't do anything for you. It takes more fuel to make more boost. Besides boost does not = horsepower.

I would agree with the valvebody and multi-position chip like Layson said, you'll see the best gains for the least amount of money that way.

ok, If I went chip is the DP then a good choice?

And valve body? Whose/which would I want to look at for my application? Are they really that difficult, or pretty basic? The whole Diesel thing has me worried. I design and fabricate anything and everything on a Jeep, restore muscle cars and do anything needed on my other cars. But this whole diesel thing has got me a bit scared.

DP is a great choice. they will do everything the transcommand does. From what I have read about the valve body it isn't too hard to do yourself. Just take your time and post up if you have any questions... I am sure someone will chime in... You can get a BTS one or a John Wood valve body... both you will be happy with.

Call DP-Tuner and get a custom chip from Jody. He'll tune you a multi-position, switch on the fly chip for your specific vehicle, and he will also be able to do some really good things for your tranny. I've had an Edge chip, Superchips, TS 6-position chip, TW 6-position, and now I run a DP-Tuner chip. I wasn't satisfied with any of the others, but now that I have Jody doing my tuning I'm far more impressed with what he could do for my truck than all the rest.

Get a hold of those guys and you won't be sorry you did.

dp is a great chip and the tw is awsome too!!!! talk to raul, he is a sponsor here and he can hook you up with a tw!

[robertk]

ok well wondering if I need a different tune for the Valve body add over the stock valve body on the DP chip? If I do I guess I should do the vavle body now and get the chip programmed with the for the BTS valve body? I tried calling but they put me to VM and I left a message at DP.

You just need to talk to Jody Tipton at DP, tell him what you're looking to do and what you have in mind. He'll direct you with his professional opinion and tell you what will work best with his chip. After a phone call with Jody, all your tuning questions will be answered, he really really knows his stuff.
