Yes we can.
Without tuning this car for our customer(and fixing the issues), we are not sure how long his motor would have lasted.
Will do for sure. At this point we are sure we want to design a quality kit for the IS-F, but we need a donor car to build it on. We could possibly ask our customer to use his car for this, but it may be better to start on a relatively "stock" car in order to make sure of fitment and to write a complete instruction manual from A to Z.
BTW, Andy forgot to post the dyno charts, he'll get those up soon.
