on my 01 I replaced the primary pump to a fass ddrp,then got the 47re overhauled,I presently have 35" tires on ,seems gutless my turbo pressure is roughly 20 psi,my diff"s are 3.55,don't want to go extreme maybe 100 hp max.what should I focus on next??

As stated, 35" tires, 3.55 gears and automatic tranny don't help. What stall is your converter? A low stall converter won't help either.

Am I better to go to different gearing before doing mods,that is probably big $.Can you buy the gears only to replace?

Does anybody know about Craigslist?

235's or 265's work really good with 3.55 gears.

 

As for Craigslist you get what you pay for. I would always opt for a vendor over EBay or Craigslist because if there is any problems with your purchase then at least you get support. With Ebay or Craigslist you on your own and might not be able to use what you purchase.

Thanks man! I think I,ll keep going with my project... gauges then smarty programmer,doing gears must be big bucks, did anybody ever switch gears before doing upgrades?How much for a gear set?I'll try E bay for my gauges, for Craigslist probably U.S?

I'll try E bay for my gauges

 

Why? We've got a few good vendors for gauges here. Vulcan Performance, DAP, etc.

Yep ,your right I'll go with a vendor to be safe.

I ran a smarty on my 98 for a while and it ran great with 34" tires and 3.54 gears. You really can't go wrong with a smarty or and edge comp, or both. Isspro ev2 gauges are top notch and simple to hook up. You already have the transmission so the big purchase is out of the way. My Dually has 4.10 and I have tossed the idea of going 3.54 or even 3.73 for a better hwy rpm.

Thanks all good info....first step do my gauges & Smarty,from there I'll see how the truck perform.Thanks again great forum!

Did the gauges pod,4" exhaust,cold air intake and added the Smarty...nice...in setting 5 just great for what I need,the ddrp keeps up to 14 psi,does the high idle and 3 cyl high idle gets enabled on your first download ?It doesn't show in the parameters settings.

It does enable it. It is on all the smarty tunes.

If you just flash a Smarty tune and then return to stock the high idle is enabled. That is how I got my high idle enabled.

Right on,thanks guys!Suppose to be in the - in the morning I'll see what happens in the morning.Amazing how quick this forum responds on any ?...good job!!

Some of have computer scattered around the house so I can keep up with the site. So like right now I'm reading over the site as I lay in bed for evening.

Gearing makes a huge difference in the way your truck feels, and drives. I would estimate you need about a 4.10/1 ratio just to get back to where you were with the 31" tires.

it would also relieve some strain on the drive line, but its not going to be cheep..$$$$$$$.

today I was test driving the truck up hills,getting 1100 egt with 18 psi turbo,this was pushing the truck on setting #6 with the Smarty,how's that for #?If I set up a J hook on the waste gate would it cool down the egt? 

If it was me I would see about upgrading to HX35W turbo (12cm² exhaust housing) and jump away from the HY35W turbo (9cm² exhaust housing). I typically can pull 6-7% grades on the Edge Comp set to 5x3, 3" exhaust (mufflered), BHAF, with 25-30 PSI of boost and be right under 1,200*F with a 8,000 pound trailer behind me.

Definitely upgrade, The HY 35 is good for about stock and stock only
