    • Renntech updated BMW Diesel tune for E90 335d and E70 X5 xDrive3d M57 turbo six-cylinder + 57 wheel horsepower dyno

      Renntech released their Diesel software for the E90 BMW 335d as well as the E70 X5 xDrive35d both equipped with the turbo M57 diesel six-cylinder motor. Renntech provided BimmerBoost with their dyno runs and the highest baseline was chosen to display on the graph along with the peak tuned figures in SAE correction. Renntech claims gains of up to 65 crank horsepower and 54 crank pound-feet of torque.

      The dynojet results gains of 57 wheel horsepower and 33 pound-feet of torque from the higher baseline backing up Renntech's claims. The software retails for $1200. Very nice done Renntech.

        yes amigo stafyrr, I have both installed and car is running SUPERBLY, last couple of days w full tank I looked at my odmeter and full tank Im getting over 40 mpg at 70 mph but at the end I do more than 95% fo city driving, I just beat the sheit out of her i race a lot and end up getting anywhewre from 20-23 mpg oh well WTF.

        On the stacking of JBD and RENNTech I believe its not a great idea a piggyback i understand TRICKS the computer and the RENNtech actually works with all the components of the car. i wouldnt try it, either stay with JBD or stay w RENNtech. One thing I musyt say and brought it out to Lenny from RENNtech the car is a monster but with the new IC the car is indeed for improvement. The car tops out way to fast and i believe with proper dyno and restructuring of the flash we can get more ponies out and of course our beloved TORQUE!!!. I have a guy who just installed the RENNtech flash I was molded by lenny and the guy is freaking happy he will install the WAGNER IC later so he will be RENNtech's GUINEA PIG and he also Lives in Florida. I will touch base with him and eventually go see the dyno runs once everything is in place!! trust me on this.

        on the other hand I havent Installed the QUAFIE, its not me, one the cost and two Im happy with whats installed

        hifi spoke to Lenny and Aly, Aly will get the WAGNER IC and then go to RENNtech for a better mapping of the Flash and IC I told Lenny and Aly to let me know so I can fly in and have my ECU programmed better I will keep everyone posted!!

        How's the summer in PR treating your 335d?

        My X5d has gotten lower MPGs due to the higher A/C use, but cant complain much at 3.99 a gallon.

        Btw, any sightings of that Vossen bumblebee 328?

        I bet your IC & tune make a good difference. Any word of Aly's upgrades?

        Not sure who it belongs to, the wheels look pretty decent.

        Yeah the distributor for the Island is AROS Y GOMAS, once they see you come int the price WILL not be changed average deal is around $4k or more I shun away from this place, nice set up but, not willing to buy from them, Id rather do business with Tire rack since I have from 2006 till today!!

        Oh BTW the car either is in Puerto Rico which I havnt seen as of yet and or it was either shipped via container or flown in which is very expensive may I say

        Rims and rubber? pretty creative name, hehe.

        Shipping vehicles there just for a photoshoot seems pricy, but since theyre in Miami, they're probably familiar with the transport companies.

        Wow, all those cars look brand new! Very well maintained plus lots of tasteful mods.

        Also, those tropical backdrops make me want to vacation there, haha!

        Thanks for the links!

        are there any 0-100 and 100-200 km/h numbers known for this tune? They would tell more then a dyno graph..... (for the 3 series)

        how come not more hp & tq ?
        I was thinking of using their flash but i would like to see 360-370 break hp with 550 tq. Do you know if its possible with rentech? maybe using a Wagner fmic as well.

        I have dynoed 312 whp with both RENNtech and Wagner and that at on day of 90 degrees Fahrenheit. We calculated around 450 lbs torque on the wheels I plan to do another dyno soon. I don't think we can hit those numbers u suggest I have the last updated version of RENNtech. No one else has had the cojones or time to go to lenny and get better results I live in PR otherwise I'd do it

        to be fair, 312 whp is pretty likely to be within the 360-370 WHP range (312/.85=367 HP, assuming 15% loss which is probably on the low side). 450 ft-lbs would be somewhere in the range of 520-550 ft-lbs at the crank depending on the driveline losses

        IMO, brake HP is meaningless, WHP and WTQ are what matter. If you make 600 HP/600 TQ and youre putting it through a transmission that has overweight internals sucking up 25% of the output you arent doing any better than someone making 530/530 with a 15% loss transmission
