If you want to supply a xb12, I'll do it again, but I'd need to do it asap or build another pipe, the race can and the new one I built need to ship out tomorrow. I did it before on a different dyno though, showed a 9 hp gain over the stock pipe with no fuel changes on a bone stock 09 xb12scg with the stock ecm.
Stock run, didn't get torque, but it's right in line with every other stock xb12.
Ran it with the RT-XB-1 and everything else stock, +9 hp. I realize that it's different dyno's etc. but the results are pretty much the same anyway. Good power/torque and still needs more fuel.
