I have installed an Anderson PMS and PMAS 80mm MAF with 42# injectors along with a Vortech V-2 and TFS heads (stock shortblock and cam) I now have code 157 (MAF below min voltage) and 124 (TPS higher voltage than expected). I have tried resetting the throttle and has a decent idle @ 750-800 rpm and the TPS reads 1.05V @ idle. The check engine light does not come on until I start driving. Has anyone else seen this problem? I called Rick Anderson and he said it not to far out of the ordinary to have the light come on for the MAF, but he said it usually isn't a problem until getting to the 50# injectors.
