I need my BB tune before this weekend! Checking my email constantly hoping I find it. Anyone know how long it takes justin to get a tune mailed out to ya after he has replied back asking if you have any specific tune requests pertaining to your data log files sent to him? He asked me if I had any requests last wednesday and I'm itching for that tune in the truck ASAP.
I just drove to San Diego for a street tune from him

(And it's WORTH the wait!)

Here is another idea, bit more extreme. Has anyone seen a L92 ported intake with a LS7 ported throttle body? Saw them advertised on LS1 Tech. Anyone have any experience? Not sure if it is worth the $425 plus $75 for ported LS7 throttle body plus cost of buying LS7 throttle body?

It might be one of the following:
Some customers may comment on a sag or hesitation when accelerating under the following conditions:
When coasting with a closed throttle and then aggressively applying the throttle. Examples of this maneuver include a rolling stop or a lane change maneuver. In this type of maneuver, even though the accelerator is applied aggressively, the throttle blade is opened slowly for up to 0.7 seconds to help minimize driveline lash and clunking.
Also in a 6L80 or 6L90 (RPOs MYC or MYD) equipped vehicle when making a hard, complete stop with a closed throttle, immediately followed by an aggressive throttle opening the transmission downshifts may not be completed by the time the throttle is opened. As a result approximately 0.5 seconds of zero torque may be commanded to allow the shift to first gear to occur.
Recommendation/Instructions:
Both of the above conditions are a result of Torque Management and both of these conditions should be considered normal and no repairs should be attempted. Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
I don't know if those aspects of TM can be custom-tuned out or not.
