[QUOTE="olaosunt, post: 15212274, member: 131643"] I posted the results of my dyno looking for advice (it made 630 rwhp and 700 lb/ft torque @9 psi but something was off) [ATTACH]61509.vB[/ATTACH] I completely get the dyno is only a tuning tool but since tracks are closed and the roads are frozen this is my only option at this time to get WOT logs I have a return fuel system and had a tune for E70 with E75(tested in the tank) I have an Eboost controller set to about 9 ps(it read more on the dyno monitor)and had the electric cut outs(pre muffler) open. First few pulls were decent but then operator car started breaking up so regapped the plugs and try again but things got worse and throwing codes0300,0301 and 0304 as we tried to increase boost My tuner said it looked the fuel trims were not responding and stuck at 1.0. He thought it could be bad 02 wide bands. Car has never had leaded race gas .Cat currently had under 4000 miles I am going to order a set but want o see if there are other possibilities I can look for before redoing. I am going to look at how the cutouts/boost controller is wired in case it may be causing power draw affecting the sensors. [/QUOTE]
