put a MBC in between the charge pipe and N75 valve you will pick up huge bottom end power and come on to boost alot faster ive done it to my car and my mates polo that also has revo stage 2 and i added alittle timming to his tune his car feels awesome now

Have you logged it to confirm that you haven't created a lean running situation?

[LZY13B]

No I haven't logged anything I don't have the equipment to check this stuff but I really need to go over the car soon and hopefully sort this out

That comment was aimed at HAR80N. Equally, you need to do the same though.

Going over the car can't really see a problem and I'm coming to the conclusion that it's a coil causing the problems the other day I gave it a rev in second and tried to put my foot down giving it a hit and it just bogged down and didn't want to go had to give it a few taps before it started accelerating again gonna sus out if there are any local shops around my work tomorrow that could do a scan for me and if that's it then it might explain why my car feels like it's getting slower haha

[LZY13B]

Just got a scan done and not showing any faults the only idea he has is that I'm using bad plugs that what I'm using isn't good for so much boost so he is ordering me a set so I'll find out this arvo if that fixes the problem hopefully it's just something small like that or honestly I'm going back to stage 1

Yeah from what I know, failing coil packs won't show up as a fault/raise a code. So it could still be the coil pack. Usually once they die, the car sounds more like a wrx and stumbles and stutters.

At least no codes, so that's one box you can tick off.

From my experience, when my coil pack died it was as Sean mentioned above, was like a wrx and sputtered badly under load. It was a very evident issue, and turned to crap overnight, not over a period of time.

Well my car isn't causing problems like just really slow in the revs under 4K but just got my new plugs so I'll see what happens when I put them in tonight

[LZY13B]

plugs changed and feels a little nicer but still no real power down low like it use to be on stage 1 i really dont get it its not a vacuum leak or i wouldn't hit full boost so it has to be the fuel reg and just running too rich cos this has no chance in frying 2nd like it use to im about to give up on this car i think its just slow

i put the 4 bar reg in the day before the stage 2 tune and the car hasn't felt the same since

I know its probably not the comment you want to hear - and you'd know your car better than me obviously.. but I wonder if there's just a bit of psychological effect going on here? You were expecting a big jump in power - didn't really get it - and now your questioning what's broken.

I know when I went the downpipe and got the 'testpipe' file uploaded on my APR tune, the jump in power was pretty minimal. If going from stock to stage 1 was like going from a 1 to a 7 in terms of power/feel, then the revised tune was only like going from a 7 to an 8 (arbitrary imaginary units for example). I got a bit more power higher up, but minimal change down low - possibly even a smidge more lag

But hopefully there's something a bit amiss, you can fix it and get the results you want. Its fricking annoying when there's some mysterious issue with your car and you just can't figure it.

As for being slow - I don't think a stage 2 polo is going to be smoking evo's and GT-Rs left and right, but they're pretty fun none the less
