Might be ok, but try the other things first (CRC and coil wrapping) and go from there.

Heaps of info in this site about all these things as they have all been covered many many times over, so have a mad search, read up on R&R, misfires, Fuel pump installs etc etc.

and go nuts!

I know I sure did. :yes:

Spent all day searching haha. How much of the coil do you wrap with electrical tape?

lol I spent years searching.  

Never wrapped them myself but I'd go from the bit that goes over the sparkplugs all the way up the shaft to the box!

hmmm... sounds quite suggestive when you say it like that. :D

Haha alright, I'll let you know how I go later this arvo :)

Sound's like R&R (rich and retard).

The stock ecu is seeing more air than it's used to so it tries to protect the engine by adding more fuel and retarding the timing. This would make sense since the problem started after you installed the fmic and raised the boost which would result in increased airflow.

 

This causes a loss of power and the misfiring feeling. You could try clean your AFM with some MAF cleaner and dropping the boost 1 or 2 psi, the problem should go away then.

 

Are you sure you are running only 10psi and not higher?

Problem(s) could be from either the Superspark coils (which are rubbish, sorry to be blunt) or faulty OEM ones.

Best to get Splitfire ones or go Yaris conversion or LS conversion coils.

Sure, none of us want to spend extra money but if your coil packs are buggered or you spent $400 when you should have spent $600 then the only way out is to spend $600.  Not $500 or $400.  

Always buy Splitfires at minimum.  Do not try and go cheaper.  You will only end up opening your wallet again to buy what you should have bought the first time.

I wouldn't not doubt the coilpacks in that assumption. I'm not saying that it is your coils either but if they're weak it shows up when boost and power increases.

 

As above, if buying new coils stay away from the bright coloured ones unless they're the bluey purple ones, otherwise OEM or conversion.

 

I'm going to entertain the R and R theory.

No I would not as there's still too many variables. Start with the easy and cheap fixes and eliminate them first.

What pump did you put in? Did you feed it a new 12 Volt line via a relay or just use existing wiring?

Some after market pumps don't like old stock wiring.

Check the coils for cracking and wrap the whole long bit to eliminate any arcing if need be.

Update:

have cleaned afm, ran stock boost from inlet piping straight to actuator. Have tried both my sets of coil packs, new plugs. So it can't be rnr or spark related. Any other suggestions? Ignitor?

If Series 1 then yes it could be the igniter, could also be fuel pump related or could be faulty AFM or boost leak or vac leak since you've disturbed the piping.

Engine needs Air, Fuel and Spark soooo... keep at it.

Ok I'll look into it

By the ecu thinking the air is going in to the engines and putting the fuel in to suit, only for the air to sneak out a leak and make the engine run rich, or even show enoigh airflow to go into rich and retard.

The ecu doesn't know if the air that goes through the maf makes it into the engine.

    • Out here E90s are the cheapest way into a sporty-ish car because everyone knows just how expensive the repairs can get. 8-10k USD for an automatic 335i. 
    • Noted. Have noticed BMW are more 'high maintenance' for sure. They've attracted my attention as I think the used car prices seem reasonable vs other options, and the extra quality overall vs a commodore / camry / corolla or similar of the same vintage is appealing, especially the interior, and they are more on the sporty side whereas the others mentioned can be more cruising or economical A-to-B only.
    • Haha yeah I know, this is SAU after all, why are we talking about BMW's of all things!? I hear you on the 'don't have to worry about it' side of things. Having been fortunate enough to be have been able to buy a brand new motorbike or two...never really enjoyed them as much as I'd have liked as you worry so much about where you park it, will it get scratched, stolen, attempted theft, knocked over, etc...and yes dirty. Older less valuable bikes you can just go where you want and park it wherever and not really worry that much in comparison. And who cares if it gets dirty! Never owned a V8, and have had my eyes on VE / VF commodores for years but with their prices climbing so high, the M3 has come into focus more as prices are much closer than I've ever seen...is it a potential contender now?...of course need to factor in the S65 'maintenance' especially and like you said general M car 'tax'. One can dream anyway. But more on the reality front - did read the whole 330i thread as well and was a great read too, both threads enlightening as I've never even driven one of these cars! I do recall 330i didn't seem to have the same amount of issues for almost the same car (turbos and related differences notwithstanding)...perhaps down to getting it earlier in it's life so looked after better than the 335i? Perhaps so as your 130i has been good and quite similar, so finding a car that's been looked after well is the especially-crucial-BMW-first-step.
    • Nice. Dont worry about the time of not running. My current skyline hasn't run since I bought it. About 8 years ago.
    • It's also worth noting that I am heavily and unconditionally biased. I've had a lot of cars including some GTRs a fair while ago. I love my BMW's now a lot. They make no sense a lot of the time and the guys on here remind me regularly that I could get something else that does what I want better and cheaper. If you're going to take on an older BMW it's definitely a commitment. If you bail on it early you'll lose money and also the ability for it to put a smile on your face. Stick with it and it just gets better.  f**k I should get into advertising.
