Hello everybody,
I have a 2007 saturn sky redline and i am having some issues with my boost pressure. Checked everything and nothing is loose or broken, but i can not get my boost to average higher than 20 psi. I have followed the lnf tuning guide and the lnf maf tuning guide. (pretty sure both of them are the ones written by back yard turbo). i have very little if any knock retard (nothing through first and second gear, showing about a degree in a few cells in third) My Desired airload tables are turned WAY up (ranging 683 to 763 in the last two columns) and i just can't seem to get boost. Max air load is 100 at 2000 rpm and above. Commanding and getting very close to .85 lambda during the entire run (was doing test and tune at the local 1/8 mile tonight). Is there something i am missing to get the boost up to the 22 to 23 psi range i hear people talking about. My car is completely stock except for hptuners. I have attached a log file from the drag strip and my tune. please help, i really need it.
