So I installed the MMR IMRC delete plates last weekend. So since we're off racing for the weekend tommorow I thought I'd put it on our dyno and check the NA and Nitrous tune before beating the piss outta it on the track. Same dyno, same tune the car picked up 15 RWHP and 15 RWTQ to make 280RWHP and 285 RWTQ at PEAK. The differences at 5000rpm were 23 RWHP and 20 RWTQ. Before I even put in on our dyno I bagged it a bit on the street and I could definetely feel it in the seat. Some will call bullshit and thats fine. I'm not here to make a statement, just posting MY experience with IMRC deletes. I will post a graph Monday when were home. :beer:
