Well, if that's the case, that's not really our turbo kit. He's got the turbo, but "HAD TO HAVE IT" before it was available for sale. We sent him the turbo and downpipe only, the rest was up to him.
Also, that truck always has seemed to perform marginal at best. For the mods he has, he's down 50hp from what we see here.
Now, if you had the complete turbo kit and had done it back to back on the same truck, I'd be interested in the results, but obviously this is probably not something an end user would do (and I understand that).
Kinda like comparing apples to oranges.
