INTERCOOLER & REAR MUFFLER QUESTION

[Scottie]

I added a Ralliart muffler and gained around 40kms per tank, power also increased marginally. When i put my HKS exhaust on i actually noticed a slight drop in power. Could never figure that one out..

Well I've kept my car pretty much stock (engine-wise), and had a dyno before and after with just a fmic. It picked up 6 kws at the wheels. I'm also about to replace the rear muffler (diff back) with a Apexi one, so I'll see what gains there are from just that at the next dyno day.

It can also depend on the dyno and settings.

Initial dyno day running 11psi with no mods: 156kw
SA Tune Day running factory boost (9psi??), dumps back exhaust, 3 port, FMIC: 136kw (before tune).

So if the dyno is to be believed, I LOST 20kw with all those mods!

Wang, hit the boys at STM up... If you dont have a 7202 or 7203, you will need one first.

I believe all versions are now flashable, someone may well correct me though.

Steve flashed my 7201 on the weekend. No switchable maps though.

Yeah sorry, I forgot to mention that. The before and after dyno runs were on the same dyno with the same weather conditions and same tyres. As about as controlled as you can get.

Some people can yes, at this stage STM cant do the 7201's...
