Thanks again everyone! Props from some major HP guys here and its much appreciated. I couldn't have done what I have without all the great resources here at PT.Net

Parish pushed them a heck of lot further than I ever will. Guess that's what surprised me, knowing how far Jim pushed them. I never dreamed it would get loose like it did. I definitely have a new respect for the truck and will never get complacent at the line again. Debating leaving them on for my next track meet at MIR.

could you post up the scan of the fastest pass or a screen shot so that I can see what the converter flash looks like.

Looks good, but I have a question about your IAT's. I'm not real familiar with the radix/alky set-ups, but my procharger/alky set-up sees a big reduction in IAT's once in boost. Your IAT's don't seem to drop at all. What's up with that.

Also, I'm fairly new to tuning so don't flame me, but what is Burst Ret and Knock Learn?

Good questions and no worries, no flaming here.

IAT's- Keep in mind that these are with ALKY, Nitrous and W2A intercooler. IAT sensor post boost. From all of my mods about all I've managed to do is keep IAT's at about where they were with 5-6psi of boost. At 9-10psi and spinning the blower so hard to get there I am assuming. So many people report much better IAT's than I can do but I have honestly seen little to no improvements after alky and nitrous. Beginning to think I need to look at my IAT sensor to make sure its working properly and possibly fit one of the fast response units.

Burst Retard : A PCM routine that looks at big transitions in airflow and depending on tables will pull timing to deter knock.

Knock Learn : A PCM routine that looks at KR long term. More KR longterm will decrease the KL value. No KR longterm will increase the KL value. 1 max and 0 minimum. Depending on KL value timing will Bias between the High Octane table and Low Octane table values. It's the routine that adjusts timing should you get a bad tank of gas.

Both Knock learn and Burst Retard, along with IAT can modify final advance. In this run you see my final advance start dropping, its not KR nor Burst Knock doing it. Its the IAT pulling it down as it climbs. This can be tuned in the IAT spark table.
