July 31, 201510 yr Hi all I was wondering at what bhp figures I'd be looking at with just a remap on a standard wrx? I'd prefer to just spend the money on a handling package, tyres, 4-5 track days a year to be honest. Otherwise I've seen the choices available....for about 280 + bhp ..2000 pounds +!!! Of course a bit more oomph is always welcome especially in the mid range. Has anyone done just that and were the results satisfactory and most importantly trouble free in the long run?
July 31, 201510 yr High flow panel filter, exhaust & fuel pump will get you around the 270 mark from a td04 turbo, so roughly 45-50bhp increase, depends on what exhaust you go for price wise, but a grand is a ball park figure all in
July 31, 201510 yr Depending on filter might be able to get 250 260 on a standard wrx :) Which isn't to bad ;)
July 31, 201510 yr the 05 wrx can get between 260 - 280 bhp from a remap (mine only made 263bhp with remap and exhaust). Depending on supporting mods, some can get 290-300bhp, but not often. The main increase from a remap is midrange power and torque, the car is more drivable lowdown. the peak figure is just for bragging with. the midrange is what really matters :)

I still have all cats and a remap made 272. Massive difference to standard, just such a smooth power delivery [emoji106]
July 31, 201510 yr Author Let me get this right...so If I keep all cats and exhaust standard and just do a remap the obtained figures are going to be around 250? maybe slightly more?
July 31, 201510 yr I'd suggest upgrading the backbox to a PPP or WR Sport, Only cost me £100 and fit a panel air filter £30. No point not doing those if you're paying £400+ for a remap. My mechanic suggested fuel pump just to be safe. And you're looking at 260-275
August 1, 201510 yr Author I've already replaced the filter (K&N)... Thanks for the info guys. Any links for a PPP backbox (or anything proven similar) to order online?
August 1, 201510 yr For those hp gains you'd need to looking at going full decat or a sports cat back system, plenty around used or if your flush new/custom build
August 1, 201510 yr Stants, for 265-270? I've not decatted. I have all the standard cats....including the one the full PPP exhaust system doesn't have. and I have the graph to prove 272bhp :D Duncan from Racedynamic (mapped mine). He said he tends to get more bhp out of the later model Blobs than the earlier blobs and bugs. Wasn't sure why but thats what he tends to see. I think it's quite incredible you can buy a 10 year old scoob and it has the same bhp as when it left the factory.
August 1, 201510 yr Yes I used dunc but ad you say he does get better results out of new age. Have you decided to keep yours then? Does the prodrive pack delete one cat and replaces the downpipe cat with a high flow cat ?

Does the prodrive pack delete one cat and replaces the downpipe cat with a high flow cat ? I decided to keep it until I move....and take a bit more equity out of the house to buy a better car than I can afford right now. So still got it mate :D I do really enjoy driving it still so not a hardship for me to keep it. Just been on a 3 week holiday and I'm like a little kid again...all excited to drive it I thought it just removed the downpipe but my memory isn't as good as it was :D
August 1, 201510 yr After a bit more reading I think you are right Stants....downpipe replaced with high flow :) ... I have standard cat on mine
August 3, 201510 yr Mine was stock bar a high flow panel filter and a different back box, remapped to around 250, a decat down pipe and new fuel filter was my next step taking it to 260. I then went STI VF35 turbo, pink injectors, decat up pipe and got to 315 (but i think with a better mapper i may have made more)

August 3, 201510 yr 03 :) blobeye Sent from my D6603 using Tapatalk Ah right. Yes, that fits with what Duncan was saying i.e. earlier Blobs don't make as much bhp as later. No idea why but interesting isn't it :)
August 14, 201510 yr Lots of people mention k&n filter. But, I have also heard that they can damage you maf? Is that right.? Sent from my iPad using Tapatalk
August 14, 201510 yr track work is very different to road, oil temps, fuel supply etc need to be thought about
August 15, 201510 yr Yes you can damage maf with an oil covered filter, you can clean the maf to keep them going longer (vids online) or you can run maf less through a remap. I have a dry pipercross panel filter atm Sent from my D6603 using Tapatalk
