With CPE Standback do you still need a fuel cut killer

[chriscecc914]

extra spent money thats the only reason i guess, i'm not saying its a bad thing i just wouldn't do it. but i'd rather have a standback, that maxes out my car now...and has the potential to max out the car once the aftermarket catches up also. besides the standback is much safer than a MBC.

there are 1000hp cars that run an mbc. I dont think its that much of a risk if you know what you are doing, buy something quality, and set it up correctly.

Also, ATP told me not to run the stock boost control solenoid when I asked them about it during my 3076r install

 

[whooosh]

the only problem I see with running the stock boost control solenoid is the FACT that is regulates boost right after a huge spike
I have ZERO spike issues with my MBC/ATP F_C_D combo
I'm going to agree with whoever said "if you know what you are doing, an MBC can be useful and work pretty well
My MBC will be my partner on the MS6 until I have the car where I want it in terms of bolt on parts....then CP-E EMS is inevitable

agreed

x2....i have no spiking what so ever. Its set to 17 and nails it without going higher

I'm not saying that all MB's are junk, but the standback is just safer. You can turn the boost up all you want to with a MBC, and your AFR's might be fine up top, but you can't do anything about the lean spot you'll get at part throttle from the faster spool. Why do you think alot of blown motors happen at only part throttle in the lower rpms...Take a look at the base map that comes with the stand back. They add boost, but they also add fuel..

cant you just tune more fuel into the lean spots with the standback?

your fuel addition is controlled by the MAF readings. if you add boost via MBC the car will keep stock like A/F's. the maf reads the incoming air and tells the ecu how much fuel to add. it will need a short "re-learning" period like any other mod, but your ecu will adjust and be totally safe, all the way until you reach the MAF max (which is well above 18psi, even in cold weather) those who knock a MBC just dont understand it. true it is not a "tuning solution" like the standback, but the results seen by MBC users is hard to argue with. so far the MBC MS3's actually make MORE power than cars with the standback. no blown motors yet either !

i have a feeling people are just trying to defend their hard earned money. mbcs are the way to go with this car untill some1 comes out with throttle control.

really where are these dyno sheets? cuz that doesn't make sense at all

search on here, a ms3 with with a modded airbox, 18psi mbc, and racepipe made 311whp and 364wtq, backed it up by going 12.7 @ 107mph in the 1/4. Trap speeds dont lie

 

[pHeeL tHiZ ViBe]

he didn't make 311whp on stock downpipe! no way!? its way to restrictive to allow that

on the other hand: in what way would that be faster than that same car, modded airbox, standback tuned and set to 18psi, with a racepipe.

that standback would achieve better results even still, i'm convinced

i'll save you the trouble.........

people just have misconceptions about some things. just like people who say.... "nitrous will blow your motor" it becomes clear that they just dont get it.

 

[pHeeL tHiZ ViBe]

well i just don't get how a MBC can be any better than the standback set to the same boost as the MBC would be.
plus the fact that you can tune your car with it!!!!! +9billion over MBC

i'm not saying a MBC wont increase your power lol, cuz i know they are great...but not better than a real tuning solution.period

well he did, as well as trapping 107 on the stock downpipe. Notice the top of the graph goes flat, thats probably the restrictive downpipe/pos intercooler doing its thing. once he replaces those two and allows the turbo to work easier and not loose pressure through the system im sure hell be cracking 340-350

give up, they make the same power, ure not tunning s*** it any of the standbacks, the reason they make any power is because they raise boost. The only benafit of a standback is part throttle driving and the ability to be an idiot by flooring the car in 6th gear at 1500rpm...u simply cant do that with a mbc. untill throttle control comes out, that is the ONLY thing you are paying 600 bucks for and ******* up ure wiring harness.

what are you talking about?

you are to tuning s*** with a standback?
therefore more power.
you do more than raise boost?
i'm not giving up.

oh really? what do you tune? you have ZERO CONTROL over the throttle and thats what limits power on these cars. The only thing u can do is a a/f ratio, which guess what are not lean or rich with a mbc, and timing, whihc once again guess what is spot on factory. the only thing you can do is part throttle boost since the stock boost control system actaully takes care of it for you. look at hp figures for every tuned ms3/6 and compare them to mbc figures. They are virtually they same and both will run the fuel pump try with mods. once cobb or cpe comes out with throttle control, thats when ill whip out my amex and actually 'tune' the car
