uh oh. you might not blow up your engine with map =/

dont run a downpipe w/o em lol.


and yes, you dont notice it too much in low gears, but highway and topend pulls are much, much harder.

also, with the mods you have, id definatly recommend a protune as well. the injen cai isnt like the stock diameter airflow.

wastegate solenoid code was probably due to overboosting since you did not have a stage 2 map loaded. Check yoru o2 sensor connections and make sure the wiring is in good shape. If thats good then it may be the sensor itself. The code might reference what 02 sensor is throwing the code I honestly dont know that. so check into it

The wastegate solenoid code is comming with the short ram intakes. I had that one night when it was 42 degrees and I opened her up.

Plug your AP and pull off the code from the ECU. It takes 2 minutes and will help you see what's going on, don't drive with codes like that, not a good thing.

Your mods are good, I would just get a CAI instead of the short ram, walbro fp and get protuned.

Went stg 2 yesterday. Defenatly worth the money. Well see what it helped at the track in a couple weeks. I do have one questoin. How do you use the code reader on the APv2? I was messing around with it after the install and even though I don't have a cel on the dash, the AP has a whole list of codes when it pulls them of the ecu.

Plug the AP in, and on v.1 I think it's option 5 to pull the codes..........

Stage 2 Officially today. Helix Catted Downpipe mated to a Perin Single Tube Catback. I am in love all over again with the car. The thing is a monster! Why would anyone spend $55k+ on a Corvette???? LOL
