01 Silverado dbc

Trying to add file

Idles great but if you Rev up when returning to idle cuts off unless you baby the throttle back down

R4B is stamped on injectors also 4156a above the r4b if that helps

All way told flow tested 550ccs per minute at 3bar which converts to 52.5lb/hr at 43.5 psi

New injector # FI03-550-8+EV6

Built 5.3 .bored to 5.7 630 lift cam stage 4 Texas am 706 heads tbss intake 92 mm tb ran decent on 30lb injector upgraded to 50lb injectors and don't know how to adjust for the different flow

So I would have to give you both devices but only get one back and give one up so I couldn't even sell it or get any credit for giving it up?

I bought a second mpvi 2 because I thought my first one was stolen well turns out I found it today can I combine the tunes I have paid for on two one mpvi2 so I sell one of them

I just got the mpvi2 and it came with a thumb drive
Is there info on the thumb drive ? Like to install hp tuners on laptop?
Or is it for storage of tunes?

I am new to using mpvi2 what is the thumb drive for?
To save tunes to instead of laptop?

Looking for hp tuner gm transmission tuning book
Need to tune 4l60e

Does 6 credits cover 99 to 07 Silverado or does 6 credits cover one year of that group ? So 6 credits unlock all 9 years or just one specific year in that group
