Lagging Power

Prokopchuk_9 · August 5, 2009

Hey I drive a 2006 sierra 1500 HD it's got the thirsty 6 litre. I put cold air intake, throttle body spacer, magnaflow exhaust and a bully dog triple dog programmer. And it still has a lag in power around 3500 rpm. Than around 4 grand it kicks right in. I thought the stuff I did would fix this issue but it hasn't. Plugs and wires are brand new. Everything is tip top I just can't figure this out. I've noticed some of the 3/4 ton Chevys I drive at work with same power train have this same trait. I'm stumped. The way it's cammed? Or is it a fuel issue? Or maybe tranny? Somebody please let me know thanks

You need a custom tune <<<See Black Bear to your left<<<

What your feeling is the torque management/delay that GM puts in these trucks.

Get a Black Bear Tune, sell the throttle body spacer and your programmer to get money for your tune.

This black bear tune will be better than the bully dog? Can I stack them??

The black bear tune will be way better than any programmer out there. With EFI Live that Justin from Black Bear uses to tune GM trucks, you have more options on what to change than the programmer. Rev limiter, speed limiter, remove delays in the trucks, removing torque management completely, changing shift points. Programmer tunes are very limited to what they can do to your truck in performance.

+1

If you can find someone that wants to buy the TB spacer otherwise you can use it for a paper weight. Black Bear will net you a lot more than a Bully Dog.

List of items that Justin changed/modified:

Idle RPMS

Shift Points

Line Pressure on Trans

Dual Tune (87/93)

Thermostat temp

Tire size correction

Throttle sensitivity changed

Transmission shift profile change (Where the truck immediately shifts into the next higher gear under very light acceleration thus reducing the low speed clunk experienced by most truck drivelines; truck immediately shifts to the next lower gear by hitting more than 45% throttle)

and he did it while monitoring the truck for an hour so he made changes on the fly until I found what I liked. I know Bully Dog can do that but my experience was better...I thought most 1500HDs came with 3.73s out back as noted above. Anyway, we had the Live tune session in Dallas back in December 2008 and the truck is still fun to drive...

The bully dog has all that too man. It made a huge difference with the tranny shifting points and firmness but their is no in between it shifts so hard into second it chirps the tire. As for the gears I did it myself. I think I'm gonna take you guys up on this guy. That lag ticks me off. Another note 1st gear makes an odd hum. Only first. Shifts fine doesn't clunk or bang into gear. It's done it for along time doesn't seem to hurt anything just annoying. And too the guy with the hd chevy this is really gonna work? It will put the bully dog too shame or what?
