Hello,
I am looking for some guys that have experience with tuning trucks with 8L90?s, any knowledgeable advice would be greatly appreciated.
Short story- is it possible to tune a 6.2L 8L90 to have throttle response and quick shifts without destroying the transmission. Possibly similar to a tuned 6.0 4L65 combo? (That has to be aiming low right??)
Long story -
I have a 2015 Silverado 1500 Max HD with a 6.2L and 8L90 combo stock other than afe intake. My goal is to build a 2015 Silverado SS as a throwback to my 2003 SSS. My issue is drivability.
As all Chevy pickups from the last couple decades, the truck stock was very ?mushy? lethargic, And not very responsive, making it very boring And frustrating to drive.
I have had it custom tuned, and was very disappointed in the lack of change.
Contacted the tuner they said it was a conservative tune and that they would wrote a more aggressive tune but that I would have to be very careful with any type of load on the truck as it could damage the trans.... it?s a little bit more peppy maybe 5% change, comparable to a stock 6L80 shift characteristic until you hit WOT. I told the tuner and they basically said the transmission won?t take any more? It holds whatever gear it?s in at 2500rpm until well over 3/4 throttle?!
To the experts out there, is it possible to get this thing to be enjoyable to drive?
new tune from someone like blackbear?
Get hp tuners and tune it myself?
Sell the truck and buy a ford??
6 speed manual swap?
