2016 f450 turbo lag, need help!!

Hoseclamp · Jul 2, 2016

Mods are in the sig, this truck is the strongest 6.7 I've had (4th since 2011), I was looking for improved mpg with a ******, a bump in power sure why not, but it runs bad. The turbo lag is awful.

I've tried a few different tuners, a BD 40928, running a SCT live wire right now, trying a few different tunes from the vendor, we are not having success. Anyone have an idea what it runs so poorly now below 20lbs boost? Can it be tuned out? I have no intake leaks, everything is tight, threw in new MAF in it also for safe measure. Any insight would be appreciated.

Give me a call. If you have an sct, I am sure we can get you some tunes that work better if that's what's causing it. 217-718-6119

I have a BD 40928 and the SCT, neither performs better than the other. Will be calling after the 4th for sure. Thx!

Anyone else notice that the instant MPG gauge stays maxed out at high MPGs even though hes giving it full throttle? It actually is going up in MPGs as the rpms are increasing. Something doesnt seem right about that.
