Well, tuning was finished up tonight. A couple tweaks here and there and good to go. Many thanks again to Louis for the tuning. He said it felt like it was at about 450 hp or so to the wheels but might with the weight of the truck, it's deceiving and may be closer to 500.
Anyway, I'm really please with it. Virgil drove it a little bit today and Louis drove it after tuning...maybe they'll throw in their thoughts...
The problem is that its a tire lathe, so you cant get an accurate feeling of actual power...
For those that care, Timing is 18 at peak Tq to redline, ramping down from 22 to help it spool, Trims are +2-5 at idle and driving, and -8-12 before it gets into boost, and 110kpa+ are zero. AFR is 11.2~ at WOT, 12.0 at part throttle 3-5#s. no knock, maybe .1-.4 here and there, but really nothing at all. At 20*, we were getting a solid 1.2-1.7* of KR, so I reduced it to 18.
IATs were very cool, damn near ambient, and only rising ~15* from a 2-5k pull in 3rd
All in all, went really well. Moze is happy
Louis
Definately not solid. just a hint after a few passes. I will have to re-adjust the offset for IATs, another degree above 100* would solve it. I have the timing retard pretty aggressive, so even the slightest sound of knock, real or false, it will start taking timing out. You never know, bad batch of gas, hotspot, boost spike, etc. Its better to be safe than sorry, and Im not one to push the limits of something that isnt my car, or a race car.

Yeah - had all kinds of pedal left but one there was a car in the middle lane and if I went WOT my back end would be all over the place (scary breaking loose at 50 +). We need to go on a nice straight stretch with no traffic - once on motor once with you on the bottle. Bottle would be a fun race.
Don't forget about the database, Moze.
