I got one fo the first kits that came out and mine came with 30s. I also switched up to the 42s.
You can compensate with the chip for the larger injectors. However, you may run into issues 'pegging' your MAF. If you have a local dyno tune/chip burner, talk to them about what MAF you should run. Each type requires modification of the program whether that is Lightning, Pro-M or a modified stock MAF.
I have a modified stock one. JMS was not able to get a good program together with the Pro-M i have sitting in the garage. This was all mail order chip tuning...:barf:
