But either way that some awesome #'s .

I was in touch with the customer today who is 100% sure he never had anything in the tank but 100% pump gas
I was thinking that his knock sensor may be slightly less senstitive than others - something I will try and test when he comes back for further tuning
In any event there was a total absense of audable knock or any knock sensor activity beyond normal engine background activity

There has to be some explanation, so it will be interesting to see what happens. I just hope that the power he's making at that boost with the more-lean-than-normal tune and maxed IJD will not damage the engine.

no body knows me but i've dyno'd many cars, dsms, evo's personal own a o5 8,
i have more work on the car than that one , and i know for a fact that this power claim is all
from a poopy dyno that reads high..............

dude you are funny....Al is one of the premier tuners around not to mention that Pruven Performance are gods in the 4g63 world and this dyno has seen ALOT of cars in the CT/NY/NJ area.
I have had Al tune my car 3 times already and his tunes are NOT a joke

At first a miss fire was suspected which resulted in a swap of plugs and a test of a back up set of spark plug wires and coils we use in these circumstances
Later, after a boost leak and compression test and a test of a second boost controller to rule out any other causes, a use of my knock ears and data logger showed that the dip was realted to the down pipe contacting the on cross member when the engine was torqing over
When the down pipe was knocking into the cross member it was apparently tricking the ecu into pulling some timing in that area of the map
Just an example of how the tuning MUST go forward IN RESPONSE to what is going on in the individual car.

Either way, holy crap.

if it was corrected it says something like "SAE" or "STANDARD"
