I have not looked at the vid I took of your car. It was only on my PHD(press here dummy) camera. 4mp stills, so the quality will certainly be iffy.
If we don't recodnise the track screw up, I would have got the fast time for the day
I'm pretty sure with a little effort, I can better my times.
As bad as you said your launches were, I believe my 60ft times were consistently .2 or off yours.
I need to run with far less fuel. I believe this will really help my ability to get off the line hard without hop.
I do have a slight boost leak. Not enough of one to throw a code, but it sure makes a funny sound. I have noticed that I peak at 130, where I was getting 145 before. I assumed that with the learndown irrelevant with my tune, that cold weather performance would increase. Even if it doesn't effect my performance, it will improve my pride.
I have random cases of knock at around 4000rpm. It happened on the way to the track, but after a few blast on the highway, it seemed to pass. I have heard of the issue with O7's, but running 94, it only happens time and again. I hear the hotter plugs from the o8's make a difference.
I would like to try adjusting my tire pressures. I struggle with launches. I am spinning well into second. Even running behind a quick car that left a nice patch af rubber for me to sick too. These tires are out of thier element for sure, but I still think that I am not utilizing them to thier potential. High profile tires would surely dampen the wheel hop although I'm sure our independant rearend will never be a star at the drag strip. I bet a set of floppy slicks would give us killer launches with better relative driveline security.
I considered HP tuners. At the time, they had not opened enough tables to convince me do grab a new laptop and the software. I wish I at least had HPT scanner to see more of what is going on. I believe that GMPP may have been gentle in 3rd and 4rth gear. It could be that my computer thinks my cat is cooking. Surely a custom tune would have the advantage if this was the case.
I don't think this can be a definitive custom tune VS GMPP comparison. I am convinced the addition of a HF cat will wake my car up...more
I did get my ass handed to me. Repeatedly......argh.
Happy to line up another day.
