Thread: Lt4 swapped 16 Camaro

    Lt4 swapped 16 Camaro

    So I have a '16 Camaro SS that the customer swapped a LT4 blower from a CTSV. He's using ADMperformance harnesses for the map/iat2 and evap. I think I'm missing something because there's just no power on the dyno. I'm only getting 4lbs of boost with no signs of belt slip. Even after getting more timing out of her, the power didn't move like there's tqmt still kicking in. Can somebody point me in the right direction? Here's the last tune I worked with the datalog from the dyno pull.

    You never went into PE until way late to hit the TQ EQ ratio table that will alter your TQ numbers. Zero out the PE throttle enable for now and you'll need to put peak tq to stock then multiply by 1.30 which is usually good. Change PE Delay to 1,500rpm. Shows 16% off on the entire pull as is with limiting and these items need fixing before looking further. When you do go into PE the car begins to correct the problem area.

    Also Log: max tq, manifold press hi res, intake advance, pedal source (2items), intake cam advance, did you pin IAT2 to the ECM?
