So for $199 you can have more power than MPPSK which costs $3200. If you throw in an exhaust such as MPE for around $950 that's still less than half the cost. You can remove it in a minute, what is your guys' experience for those that have it on the B58, any issues with check engine lights or drivability, drivetrain malfunction, etc.?

[riskmaker76]

Check Engine, yes some times, Driveability, poor most times, drivetrain malfunction, probably not..

These quick boosters are quick fixes - you cant expect the same level of all above compared to MPPSK or even the JB4.

And the MPE is a waste of money on this car... unless you remove the resonator.. then MPE plus that is great..

If I were to do it all over again coming from a MPPSK with a JB4 - the most expensive option I would get

JB4 plus new mid pipe plus new muffler - this is the best option honestly

Thanks for the info. I've been thinking about mppsk trying to get the best deal locally and like the sound of the exhaust. I guess you get what you pay for.

MPPSK is a waste of money.

For that kind of money you can go FBO and make a ton more power.

You cannot go wring with a JB+ on a stock car.

We offer 14 days money back guarantee if you wish to give it a try

jb+ has poor drivability. Low speed gear changes were atrocious and barely increased peak power. My personal opinion but do a search and there are others who say the same.

I've had all sorts of tunes and a proper ECU tune is always smoother and safer. It's more expensive but I wouldn't say a waste of money.

We've had some good success with our customers with JB+.. Sometimes the boost needs to be lowered as it runs too hot.

For the price its hard to beat, but you are correct a proper full tune like the JB4 is always advisable!

Until B58 flash tuning is available, MPPSK and JB4 is the best way to safely get the most out of the car, currently. There is a slightly higher fuel ceiling with the MPPSK and the JB4 allows you to run as safely as possible (as long as you configure it properly and datalog a lot to verify). Without datalogging, you have no idea how safe or unsafe your piggyback is running, no getting around that fact.

If you have the money, MPPSK and JB4 is the safest and smartest way to go. Otherwise, dilute it however you like.

Do you use a custom map or one of the stock maps? Do you use a different map in comfort vs sport?

Here are my daily settings: http://www.n54tech.com/forums/showthread.php?t=47581

I switch to Map 4/0 a lot just to see how the stock tuning reacts to current fuel and conditions. I rarely run meth on the street.

Comfort vs. Sport makes no difference to me in regards to JB4 map. I have Sport set up to only stiffen the suspension. I go to Sport+ only when I want the exhaust to be obnoxious.

I basically run Map 6 with an E25 mix, and Map 4/0 when only 91 octane is available. The additive/non-adjustable maps do not run well with the MPPSK since they are both trying to increase boost at the same time. This creates conflict and the power is not smooth at all.

I have to disagree with your last paragraph. It took about 5 miles but maps 1-3 work great with my MPPSK. This week I've been running 5 but I'll probably go back to 3 as my daily. No issues.

The MPPSK exhaust noise is the same in Sport as it is in Sport+

What sort of power are you getting with the JB4 and MPPSK??

[riskmaker76]

Dont even think to compare the two -

you get a sloppy power boost with JB+
MPPSK is smooth and linear plus the exhaust with flap control (from stock to very loud)

If you want smoother acceleration get JB4 plus exhaust - that is most compared to MPPSK - but dont care about warranty

JB+ many complain on shifts, smoothness, check engines (rare albeit), etc.

Now if you dont care about drivability and the potential of check engine - then JB+ is for you.

MPE is useless without the resonators removed... get a full catback exhaut OR just remove the resonators (dinan makes a mid pipe).

I'm getting the mppsk installed in the 30th. Thanks for the info!

[F82Tazmanian]

Had the jb + initially. Then went MPPSK. Not even close drivability wise. I haven't used jb4 since my 335is but a factory flash tune monitoring all engine parameters (not just afr and timing). No contest. It's expensive but no hassle. The exhaust sounds ridiculous if you do sport + with the crackles. It all comes down to cost. People will always advocate cheaper tunes but I've had every piggy/flash on Audi's and bmws. Stick to the flash + warranty for sure.

[riskmaker76]

Its expensive - but if money not a factor I guarantee you will be happy..

and if you need a tad more - throw a jB4 on like I did... grin from ear to ear

Can i just check, is MPE being mentioned simply the 'silencer' part of the M-Power exhsust system. Just seen a few videos of the full MPPSK and I'd certainly like the pops and bangs, but can't justify £2k on an exhaust system

Edit; Also, JB4 is what, an ECU remap?

[chris-c]

JB4 is a piggyback unit that tricks the car into producing more power. It give a decent chunk of power but it can result in driveability issues and you might need to tweak it.

The MPPSK is a full exhaust system with a BMW remap. BMW are the only people who can currently remap the B58s in these cars and the work doesn't impact warranty.

The full MPPSK can be had for £1650->£1700 if you call around and it transforms the car.

As mentioned by Chris c the mppsk is a remap so it also increases horsepower and torque this it costs more than MPE. The DME for the B58 has not been jailbroken so only BMW can do remaps for now.

[NooBish AbbZ]

thanks for the replies gents I've been looking at the MPPSK this morning. I am so damn tempted, especially because as a person I'd want it to be done by BMW and be covered etc. by them

Concerned it'd be far too loud on a motorway though. I've found a brand new set for £1500 on ebay with just a very quick look, though I'd want to go for the carbon tips. What's the sort of going rate for fitting of the entire system?

[chris-c]

£1650 is the going rate at Cooper Reading and one in Warwick.
Ask around and ask them to price match.

The noise on the motorway is next to non existent if you put it in comfort. Put it in sport/sport+ and you'll hear it for sure!
