Hi everone..this question may have been asked to death...but can a few people with GSR Hybrid coupes tell me about your mods..and any quartermile times...and dynos....

i got a gsr in my si coupe...163.5 hp to wheels...i/h/e skunk 2 manifold...bbk 70 mm tb..itr flywheel...my setup ran 15.2@93.5 then took it to get dyno tuned the next week..baselined 130 something hp with vafc set to zero..after tuning picked up 30whp...so maybe mid 14's...

 

sweet....man....your baseline dyno was only 130? is that suppose to be right? All in all sweet times...im hoping after my swap to hit low 15s with just i/h/e but i guess thats asking for too much.....hehe..we'll see how it goes this december after the transplant..

baseline was 130..cuz i'm running the wrong ecu..still a b16 2000 si ecu...adding about 25-30% more fuel via vafc..when on dyno..with vafc fuel settings to zero..the air/fuel ratio was like 19:1...waaay lean..enough to burn a hole thru a piston..that's how 30+ whp was gained

 

ahh i c...so instead of getting a GSR ECU..u just got an VAFC to correct the problem?
