    Sluggish After full delete and efi live tune

    What's up guy's. Ok so here is what I got going on.... I just did my 5" turbo back by mbrp, edge cts2, efi live by Ryan, full delete, S&B CAI, & 3.5 Pusher horn... ok now that being said my truck now sounds great like a jet engine however I have no power at all. The truck has 14k on it so wear and tear is not a concern as of yet. I have cleaned all sensors including MAFS. Still no power gain. Does anyone know why my truck sounds like Tarzan but runs like Jain?? Any help would be greatly.

    Appreciated thanks in advance.

    I called Hardway they said that it is not tuned for the intake and they would need 100bills to rewrite the program. Now I know a bunch of guys that have all the same thing are having no problems at all and don't have to retune? I'm stumped

    How long ago did you purchase from Hardway?

    Well I bought everything all at once. Put it on 2 weeks ago. Truck ran like a champ before the mods were maid. I've cleaned all sensors with MAF cleaner by CRC. All sensors were shinny brand new but cleaned them anyway. The only thing I have not done is battery disconnect yet to start a relearn. I'll be putting grid delete in and pusher pipes to moshi inner cooler In the next few weeks to see if it helps at all. I'm also thinking of hooking auto cal up and updating software on it to see if that makes a difference.

    Is EFI different from other platforms somehow? I have similar mods as mentioned plus 90 HP injectors, and have had no issues. I've used Smarty, RaceMe, H&S, MCC, and Warp. No issues with any of them, but mine is a 2012.

    If you do not get each mod tuned in there then the truck will not run right. These new computers are very picky about what you add to the truck. Something was probably failed to be mentioned prior to tuning.
