Seems I need some new mods to get a map

hi guys

I have an Ed30 with BCS prestige system with sports cat and Revo Induction.... Just messaged R-Tech and apparently I will need to go Stage 2 and bypass Stage 1...

which is cool, but now I need to source an RS4 valve (seen some at awesome so will get one from them) and a front mounted intercooler..

Anyone know whats a good front mounted intercooler to go for? I don't want to pay through the nose though as didn't realise I couldn't go Stage 1 so this is extra cost I didn't account for.

cheers for any help and links

Phil

Hi mate. I recently went Stage 2 R-Tech, also with a full Powervalve with sport cat, and a Pipercross panel filter. Those were the only engine mods.

After the map it would often get fuel cuts under load. I got it scanned, which confirmed I was falling a fair bit short of meeting requested fuel pressure. I then had a Loba uprated fuel pump fitted, and was advised that an RS4 fuel return valve would also help (I'll be getting an RS4 valve very soon). It's worth remembering the RS4 valve is only really beneficial if your pump itself can meet requested fuel pressure. So I'd look at getting an uprated pump as a priority, as well as an RS4 return valve. This will be more beneficial than an intercooler at this point.

However, if you do have the budget, a Peron intercooler is one of the best on the market for k04 cars. A more affordable option is an S3 or mk6 R intercooler. Still miles better than the ed30 cooler but maybe not quite as effective as a Peron or Stage 2 Airtec.

I wasn't expecting fuel cuts just with a Stage 2 map, but it seems the map was requesting loads more fuel pressure than the standard pump could provide. I'm still on the Stage 2 map, and it's running beautifully now. Had I known before the map that I'd run into fuelling issues I would have fitted the Loba, an intake and an uprated intercooler, then gone for the full fat Stage 2+ map. Maybe that'd be an option you should consider.

If you're unlucky you can get a poor AFR at stage 1. The OE pump can be a bit marginal at certain revs.

awwwww man I've got the same mods and they told me i have to go to stage 2 aswell. i only want like 300hp though stage 1 would do me. but he said he wouldn't do that.

i don't want fuel cuts  :scared:

Yep, it's one area where the TFSI could have done with a better pump from the factory. I understand the later TSI engines don't have this problem?

My advice to anyone taking things seriously, even mild tuning to Stage 1/2 levels, is to prioritise the pump before other bolt-ons.

Downpipe and pump are the first bottlenecks to address.
