I am helping a friend with his 2014 camaro ss, he has longtube headers, catless exhaust, stage 4 cam 233/248 619/595, and upgraded valvetrain and pushrods. from 1600+ rpms the car actually runs really good and even 1500 isnt bad if we are in 4th gear or above. however 1st 2nd and third do not enjoy steady light throttle at 1500 or below. I understand I might not be able to eliminate it completely, but I was hoping to get it a little better than it currently is. We started with idle tuning, it sits at 975 with a wonderful lope, steady maf and pretty consitent spark, then we did VVE tuning followed by MAF tuning, all of this was done with the short term trims histogram, we wont have the wideband untill this weekend. I have attached our last drive around, and last tune. All help is greatly appreciated.
