nice set up .... looking forward doing that same thing....

 

bigric, that like me asking al for his cable, see where i'm coming from?

 

Datalog your wideband on race gas today at high boost and send me the file. I will help you get the tune dialed in better for the track tomorrow. It will be hot tomorrow and humid, so I dont think even with a perfect tune that the car will run its best. You will probably have to wait to a cooler night to get that 11.8 ... But it wouldnt hurt to get the tuned dialed in better.

translation of i need your cable = i need you to flash my ecu... but i either way i didnt realize we were cool like you and al, thought we were a little different

 

thanks brian. i'll try and get that done today.

 

the evo 9 turbo is so impressive. I got an evo8 and threw on the evo9 20g 6 blade i never had a chance to get it dyno tuned due to some catastrophic problems but....it just pulled harder and felt like it wouldnt stop pulling. Im now treading in my 8 due to the problems and getting the nine in a couple of weeks and gonna start of new but im gonna sell the 20g turbo

 

matt where did you post the madness ? off topic i bet lol

 

Bump for an update on this.....I see you got your 11.8 but I am curious how your tune changed from the 8 to the 9 turbo.

Also did loosening the wastegate arm help recover spool as well as reduce boost creep?

 

i kept the same custom street tune installed when i changed the turbo and exhaust manifold. no changes were made to the ecu for pump gas. all it did was lean the afr's out a little bit from 10.4 afr to a 10.7-10.8 afr. the car runs great on 93oct and 22psi. i didn't loosen the wastegate arm yet because the boost creep seemed to work its way out for the most part. it creeps maybe 1/2 psi on the boost gauge. not sure why the boost creep went away but it did and the car is running great!

 

Do you mind sharing what your mods are? besides the obvious new turbo...

 

basically equivalent to buschur stage 4, plus 9 turbo and br ported and coated exhaust manifold.
