I put a bigger pump in and while it helped a bit, I'm going to have to pull the intake and change the injectors - not a job I'm look forward to. Its going to be a 6 hour chore.
Just when the turbo gets really going the AFR goes lean 15:1 <<< ugly lean ... and the data log shows the injectors are at 100% duty cycle they just can't pass more fuel. So out come the stock one and in go the 36# ones I have on shelf, the next jump in injector size that I have ready is a big jump 72# whoop ass << these suckers will support 130HP each! hmmm 130 x 6 .. hmm eeek 780HP <<< time for a TH400 ....
