Okay so long story short. In Denver CO, I had my 05 srt4 engine swapped out due to other blowing up. Last motor had 1000cc injectors, intake. 57t turbo. Exhaust. Bov, fuel lines for E85, and upgraded fuel pump, maybe more. Well shop got a stock short block with about 34k miles. Shipped back to salt lake. Paid a buddy to get motor running. Now won't past 3k or 4500rpm. Not sure haven't drove in a while. But when just revving it will redline. But while driving it cuts out. Is this a tuning issue ? Last tune was for the built motor. But there was a stock tune on my diablo but that still won't let the car go past 4500rpm. Still acts the same.
