Lund Tuning ProCharger Poll

[ProChargerTECH]

2015 GT PP 6spd, IM running HO kit, D1SC head unit, FRPP 52# injectors, KB boost-a-pump, 4.1 pulley, long tubes, and 3" MBRP Race. I'm not running PCV into intake, but still have IMRC hooked up. not tuned by Lund. My is tuned by Dynotune Motorsports , Brian Turner, he has tuned all my cars and bikes. i have zero drivability issues, no bucking, surging, whatever. car drives like stock out of boost. car made 631rwhp 526rwtq, on 93, with 14 degrees of timing

Thats exactly how it should run. :cheers:

And thats killer power with that timing, and should be right in line with 93 pump gas!

Everyone with a similar set up should be right there with ya!


Thanks for the post! :cheers:

By such a small amount, unless you had testing equipment and a loaded test cell, with constant temperature you "might" be able to see the difference.

In reality there is no difference at all. (they are actually the same impeller, the P-1SC-1 is just cut down a tiny tiny tiny amount) ;)

So no there really is no difference, nothing at all that would cause a tune difference. Nothing at all.

Then why not let me try or buy a tune from your complete kit and see if it fixes the problem? It should be a cookie cutter tune that you tailor to my ECU. Would love to try it.

i see a lot of people running more timing, but my tuner said he like where the car sits at on that timing (he tunes more for drivability and durability than the most hp he can get). i trust his decision, thats what i pay him for. he has a twin turbo fox making 950rwhp on e85, and a single turbo fox making 800rwhp.

the twin turbo car made 580rwhp on a 150k stock short block for years before he put the R block in it.



the one thing i see from my tune that i compare with others is my car makes more torque than most cars at the same boost level, and some running more boost. i was really pleased with that.

Procharger HO kit p1
8.1 lbs of boost
3.85 pulley
545rwhp
439rwtq
Lund tune and still surging at 3k not as bad as the Procharger 1st tune but it's definitely still there.

For comparison i have the same set up as you, tuned by dgr i made 564, 466

I have already explained to you why we can't sell tunes, and defiantly not for a D-1SC. If we didn't do CARB certifications it won't be that bad, and thank VW for now making our jobs that much harder.

You might want to get in touch with this guy....he is lund tuned.

I drive my P1 car almost daily, and have no issues.

8psi, and normal pump gas that sounds right on.

at 9psi, she would be 580-600rwhp.

Killer numbers man! :cheers::lol:

the new tricor pcm is such a finicky lady. I can make over 900rwhp on E85 on a d1sc stage 2, but she won't stop bucking at part throttle :(

You are right. In trying to figure out what's going on. I have been experimenting driving methods. It is definitely not a surge valve problem. I get bucking even when running up to 3 or 4 psi at constant throttle.

You are right the car teeters on not going as fast as it should at a pedal position or going too fast or bucking. It's like it's confused as to what it should do at that throttle position. But only in certain load ranges that evidently I go into A LOT more than others.

Another clue is when the car does not go as fast as it should and feels like something is holding it back after a shift, if you give it more throttle it should haul ass, but doesnt. The engine makes a weird sound like it's trying hard but doesnt. And the factory boost gauge will show boost but the car isn't going like it should.

I think the torque and inverse torque tables are tge culprit like you suggested.

First off, if youre using the ecoboost gauge, chuck it in the trash can. It goes off of inferred load from the pcm. If the load tables in your tune arent right, and most of these tunes aren't nailed down like they should, it's just guessing. Use a good mechanical gauge to read boost.

Second, the torque/inverse tables are tricky, and they also help with the cam mapped points. The demand tables also play a role in this too. It's very difficult to dial them in remotely on a manual car due to the gearing.

Finally someone says that...

Its been getting really old of customers calling in about "low boost" or "high boost" and then you find out they are using that dang EcoBoost gauge, and not a standard mechanical type.

That thing is so far off in most cases, people might as well use the "Dyno App" on their phone to compare power numbers. LOL

Seriously, standard gauge, mounted in the vent and be done with it.

I think so, i was happy with that. I have had no problems with my kit drives like stock, untill you hit boost then it gest fun. I have the 3.6" pulley sitting in my living room now

Any chance it could be right? My p1sc with 3.4 pulley is showing almost 11. That seemed right to me.

Oh then here comes even more fun.

Easy way to find out. Borrow a "normal" mechanical gauge, and pull it into the vacuum tree that we supply with the kit (we put 3 ports on it, so you have room for a gauge to get signal from) and find out.

Finally got my car back today and the surging is completely gone. Manny from HPP has it dialed in perfect. This is with a p1, 3.4 pulley on e85. I completely forgot to ask how much boost because I was so excited to get it back.

 

[z06psi]

Going to guess 16-17 psi.
