AFE sprint booster ?

Any info or personal experience with this ? Wish they had a TSB or Ov tune for the 2.7 6 speed. Wondering if this will solve some problems that owners face with the 6 speed (hunting gears)

If you can hold tight, HPTuners is releasing support for us.

 

will it be for the 3rd gen automatic transmission? I read OvTune was only doing 2nd gen 2.7 for now ...

 

Oh whoops, my bad! I didn't realize you were a 3rd gen.
Okay then the Sprint Booster will address any of the drive-by-wire wonkiness you're experiencing.

 

Yeah it’s really bad. Been dealing with it for 4 years almost. Now with 285s it’s worse. Etc button helps but I don’t need it holding high rpms. Only hit the button for long hills and that’s rare for me.

 

A header will do a lot more than the throttle booster, it does not increase your power one bit. It simply causes the throttle to open quicker, although I have a Peddle Commander and a header. The power from the header, will cut down the gear hunting and the Peddle Commander can be fun at a red light! Course you have to pick your battle!

 

Header on a 2.7 makes a minimal difference in actual power. Placebo pulls strong though.

 

If you don't know what your posting about, then why do it? Posting a BS opinion about something is not helpful for anyone!

 

2.7 mods here are extensively covered and proven with dyno sheets by tooter.

Header alone is not nearly what you suggest it to be.

 

Are we bored, then I leave you to yourself!

 

No opinion, and no BS. Just facts I can’t keep to myself. Not sure how well you read but there’s colorful graphs also.

Knock yourself out.

 

Placebo is correct. The only thing you can do to fix power is to supercharge it or put 5.29 gears.

I posted this thread to inquire about throttle response opinions. The new logic and transmission for the 3rd gens make it sluggish when it comes to throttle input.


But looks like 5.29 gears is on my list

 

even if you can get 10whp and 15wtrq more than factory at 120whp/140 thru much of the rev range, you're probably gonna feel it and see it in performance numbers. especially if you have a lighter model. less will be noticed with a 4x4 or extended cab with bro-dozer sized tires and lift on it. But if you have a near stock model that is lighter in weight, the header alone appears to be a good idea to rekindle some love the truck or to combat a minor upgrade in tire size.


130hp/120 = 8.33% increase

155trq/140 = 10.7% increase

lets say you have a base model like I do. no frills, no nothing at 3150 curb

3150/120 = 26.25
3150/130 = 24.23
1 - (24.23/26.25) = 7.7% increase in lbs per hp ratio.

In the performance world, it's common to spend $70-100/1hp increase depending on how tuned your stock setup is.

I think you can get a header for $450-500 shipped. 500/10 = $50/hp = good deal in most mod worlds. $6,000 supercharger kit for ?80? 6000/80 = $75. header will help future supercharger kit if you go that route. some sports cars that aren't already forced induced are paying over 100 per hp increase and to see gains from a header AND it requires a tune on top of it.

Gears are always an option and not in many people wheelhouse for home install unlike a header. finding the right used rear end for a 5 lug setup is a little difficult as well. cost for an average upgrade here varies widely for used vs new and then paying someone $115-$180/hr for install at least doubles the cost for used parts if you swap out just the 3rd member.

 

Nobody saying it’s a waste of money, it just doesn’t deliver the results that are being portrayed by the previous poster. Tooter saw good increases but he also had intake, header, exhaust. Not just a header! And his numbers are documented as such. He even states himself the header difference was negligible in itself but with additional mods that on their own would offer less benefit, they all have slight increases when used in conjunction with each other - and it’s documented, not seat of the pants placebo and mental and emotional justification. Peak torque dropped 600-700 RPM if I recall right, which was something like 3200 RPM with the mods (including AC and power steering delete), as well as lighter wheels and lighter HRR tires at a high PSI of 40.

Anyway, nobody dismissing the 2.7 but if anybody is putting out BS opinions it’s the guy who thinks a header alone has changed the driving characteristics of a 6 lug access cab auto trans to a significant degree.

 

Yeah. I'm not a fan of the ac and ps delete he had.

I'm a little more concerned about how the Air fuel ratios end up. Most engines would tend to lean out if you do both an intake and a header. I havent researched this setup much though. Sometime the computer wont add enough fuel bc it's simply not within its closed loop parameters to adjust that much. I do however think swapping out a header is better than doing an intake in many situations. There's actual resonance issues that cause tuning issues with intakes and often times it's just not worth changing the intake out. I think I may only do the fender elbow mod and possibly add another intake port to the lower airbox that reaches to the front of the truck.
