blacktundra1. if your 4.7 is the same as my 4.7 2005, stock engine HP is 271HP.
than you should be able to increase your engine HP to 326HP. stock is 210 to the rear wheel's i got 246HP to the rear wheel's. BUT i also added a volant cai, jba headers, & a magnaflow cat back exhaust.
total engine increase is 55HP, & total rear wheel HP is 35HP.
hope it help's.

Nice work. I tuned my '05 4Runner (same engine) to 235 AWHP with a Volant intake, Magnaflow exhaust and tune. Looks like the headers would've given me another 10 whp.
First off, let me say I value everyone's opinion and posts. I'm seeing a lot of negatives toward the chip and not much positive. Unichip makes very good points and sense to me as well. But, I still have my chip setting in the back seat instead of under the hood b/c I can't decide what to do with it. I go back and forth from reading this thread.
I know there are a lot more people who participated in this group buy and only a few of them have posted here. I would like to believe "no news is good news" from the silent participators and that this thread has naturally become somewhat like the local news, where mostly problems are reported. But, I would like to hear some honest, solid praise for the product before I install my chip.
I also would like to thank Nola for really going above and beyond the call of duty with this GB and that I am very impressed with Unichip as a company so far.

well, even with the can tune, there is a definite increase in pickup and throttle response. Im going tomorrow to have a custom tune, and ill let you know how that turns out tomorrow night hopefully if I have time. $100 a hour isnt too bad. The shop im going to says it should take from 2 1/2 to 3 hours to tune. My 01 tundra with the unichip was gonna cost $500 to tune, so i never did.

So correct me if I am wrong, people with 5.7L Unichip wouldn't show any gain in hp but 4.7L would?
Hello all my name is andrew (sandimasauto.us) and i did the custom tune on the ryder276 tundra. I would just like to say i was only able to get steady 2nd gear pulls. I use a mustang dyno and they are setup to run as close to 1 to 1 gear ratios, so the #'s you see are low on the dyno runs, also, if you do the math i think you would find the gains to be greater, but that being said the gain at peak is around 10% but the gain overall is more. Unichip is the best piggy back on the market, and we tune them all, we even do stand alone systems like motec and efi. We do a lot of tacomas, and if the tundra is the same, i think the big problem is the factory tunes. We have seen afr ratios from 11 to 14 with only intake and exhaust work so i think the base map may need some work to get it to work on your tundra. my2cents
Thanks for the comments. The reason you are seeing the AFR's all over the place is because this is what the stock ecu does on its own. We don't understand the Tundra's ecu and its enormous amount of different maps that it uses depending on certain situations. I explained it as best I could in one of my previous posts. The Tundra will go as rich as 10.5 or so to over 15 stock depending on the load, duration, throttle position, etc. The Unichip adjusts these values by a couple of points and they are still within the safety zone. A dyno somewhat confuses the Tundra and its sensors because it doesn't understand what type of situation it is in and the AFR's will be all over the place. You can't dyno the truck in any gear but second or it will downshift. Unichip left some power on the table, its not tuned to the max and every truck is different. They could have shipped them without a map like other tuners and left it completely up to you, but they chose to not only offer a stock map, but tuning based on NUMEROUS different popular intakes, exhausts and headers. If anyone is having issues, you should call unichip and if necessary, you may need a custom tune. Unfortunately, these trucks really need to be road tuned instead of dyno tuned.
So far, my chip has been great. My truck is more powerful and smoother running. I'm almost through my first full tank of gas with the chip and my mpgs are now at 14.9 when before it was at 14.2, and thats with a few full throttle runs just for fun. I'm sure it will get even better once i forget its there and drive normally again. I'll be filling up with 93 octane soon and flipping the switch and I'll let everyone know how that works out.

I just got my tundra custom tuned at San Dimas Auto, and got some pretty good gains versus the canned tune unichip gives.
Flowmaster exhaust, Volant CAI, JBA headers, and Unichip in 2nd gear put out a max of 256 ft/lbs and 250 hp. After the tune it was up to 279 ft/lbs and 268 hp.
Thats a gain of 18 hp and 23 tq.
I would post my dyno print out but the scanner is busted.

The tuner couldnt get my truck to dyno in third, -it kept down shifting to second so thats what these runs are at.
First run done with no unichip, #2 unchip with unichips map, #3 custom tune.
yeah he had the same problem with my truck. Man, it does not sound pretty having your truck dyno'd. Never heard her hit the rev limiter like that. Apparently the 8hp and 9tq your truck made more than mine has to do with the difference in our exhaust setups. Guess Andrew did a great job with your custom exhaust. When i get some extra cash ill be doing the same.

Sweet man. Those sound like some nice gains after the custom tune. Did you even bother getting a pre-unichip dyno run? Now let's see that RCSB rip on the track!
I am planning on getting mine custom tuned as well because I want to maximize performance gains. I am hoping to get mine done next weekend.

Uhhh...I hope those are not the numbers from a 5.7..

yes a 5.7 in 2nd gear. I was told that the gains are greater in higher gears, but it keeps shifting to 2nd on the dyno, no matter what you do. I guess this is the reason Unichip never released a dyno sheet.

Don't worry too much about that. Heat is what you have to watch for on chassis dynos. You don't have the same air flow on the rollers as you do on the road, and that can cause heat buildup the truck would otherwise never experience. Make sure they have enough fans aimed at your truck to cause gale force winds, and give lots of time between pulls to cool down.
no there wasnt, we just started from the can tune and worked from there. on A map for premium, he added a 2 degree advance as well. With B map (regular) Unichip pretty much had the timing down.
Here's the question I have, I noticed other guys are dynoing at 315-330 to the wheel. Does this mean that our trucks put down more hp to the wheel at higher gears, or does hp/tq numbers just vary that much from dyno to dyno?

Usually you dyno in a 1 to 1 gear (ours is 4th gear) and then the dyno operator just puts in the rear end gear ratio.
Your dyno operator had to put in the ratio of 2nd gear, and maybe it wasn't right.
