180 remap, where and worth it? - Page 3

You'd probably be best contacting him directly.

I've dropped him an email, fingers crossed for a reply

no offence mate but anyone who knows anything about nasp tuning will be rolling around on the floor laughing their asses off at that claim.
If the car was healthy and had a decent induction kit it should have had 185 bhp to start with ?!?!?
In reality you would do well to make half of that claimed gain without adding other mods.
On a turbo car yes no probs but you cant turn up the boost on a zs 180, all you can do is optomise and tweek and there just isnt the potential for gains like that.

Got to agree with Dave here.

No engine breathing hot air will make decent power.

As Dave rightly says, nasp tuning is much harder than turbo.

I spent many hours on a rolling road with a zs 180 so i know what does and doesnt work.

No zs 180 will make 198bhp without decent air induction system and cat back exhaust.

As a matter of precaution, we would do a health check on any car we was tuning before any mods took place. The zs needed to be 100% healthy to start with or it wuldnt give the gains.

What he probably meant was from stock power figures to breathing mods expect an increase already seen which is half that or more. Then add on the remap increase and you'll be there or there-a-bouts not in one hit as stated.

Quadcam24 · 19-03-12, 07:15 PM

add a de cat in there george too, and you might just make it.
Wirlys always made good power and thats the spec he had, inner wing induction, cat back and de cat, re map, iridium plugs.
Having said that wirlys car wasn't quite the norm, weve both seen similar modded zs not make that power.
He said he brought it off the guy who brought that 200 bhp btcc replica, the special legit one, i cant remember who built it, was it wsr or mg s & r or similar ?...but anyway the guy said wirlys was noticeably more powerfull than his 200 bhp btcc replica....and that was when it was standard !

I spent a fortune on my last ZS. was running Andrew Morrisons custom carbon fibre induction kit, janspeed manifold, janspeed sports cat and a custom back system.

Made the heady figure of... 183bhp

you've got to have very very deep pockets to tune the kv6, that's the main reason why i went T series for the touring car project

Quadcam24 · 20-03-12, 06:57 AM

true, it is a bit of a dyno lottery though, you could have made 200 if you had tried a few dyno's.....that just proves how pointless the whole thing is though,lol

Aways nice to read some positives...................

It's also likely that you can get good and bad engines. That's the problem with mass production!! You never know what you end up with? Sure the engine will run and make some power but the only way to get reliable and consist power figures would be to Blue Print the engine then make it breath better!! In theory a 2.5 Kv6 should make around 240 bhp!! However in the real world that doesn't happen but it should make 200bhp with a decent intake and exhaust and a optimized re-map!!
