I was seriously thinking Abbott until I realised that the car would be off the road for a week... waiting for the exchange.. and the cost was more. So I went PPC stage 1 and am always waiting for tomorrow morning to take her out again on the open road.
The Way to go.
With the abbott as you can see in the graph, it has big power in middle high revs, at low revs is more progresive and in some situations it has a few "lag", it looses some punch at low, but looking at the turbo gauge you can see that is the ECU that is limited it mantains the safety features to avoid a overcharge for example in gearchange and so it is more elaborated and also you have a good "punch".
I could see some dyno charts of Aero's and I can see some differences in the 2003 and 2005 versions...
this is the dyno test of my 175bhp vector with the original ECU, this torque and bhp curve you can translate it to the Aero but with more torque and power in the first Aero's of some friends and mags have a very similar shape, but in a 2005 Aero of one friend it change a lot....it has more torque, the 90% at low revs, it is like the abbott but with the max torque about 2300revs and incredible flat line to 4500 aprox. as anyother Saab turbo, the problem of the BSR is that increase the torque at middle-high revs but loosing the low revs response.
it is quite recommended.....i made the same, during the change of the ECU i installed the sport chassis, but without the sway bars there is only 1mm of difference, 24mm for the vector and 25mm for the Aero,it could help but....to change the installation time is quite big. I also installed the rear spoiler, and now i am searching who makes a carbon fiber dashboard I saw it at a gallery of the Singapur autoshow, but i don't know who makes that.
mbr performance, a french Saab accessories company makes a carbon fiber kit, but I send to them many mails but they don't answer to it, I think that i will spend that money in a hirsch pedals or the new steering wheel
