I agree on the less fuel, but the 83x74 in a .90 your gonna see some drive pressure issues above 4200 or so.
s468 68/83/.90 is all i know trying to figure out why it snuffs at end,
maller housing and gate.
Also, not running enough timing will cause it to fall off a charger early too.
That is odd, completely different than what I experienced. Around 32 degrees my truck would snuff about 32-3400, dropped it down to 28 and the thing would get below 3000 before it would snuff.
I think too high or too low will have this affect (I dunno, I've been wrong before). Last year I made some changes and forgot to bump my timing back up and pulled with it around 20 degrees. EGT's were HOT, flame was about like your avatar pic, drive pressure was thru the roof due to a .9 housing and small turbine wheel, and it fell off the charger at 3400 rpm.
Figured it out, bumped timing up 8 degrees and ran it the next weekend and didn't fall off the charger.
1.10 didnt work to well, might hook agin on it. 1 rst 2 times T case didnt go to 4 low and was trying 4 high and didnt know it .. fixed the linkage and went to another pull and got it down track it ran 3500 rpms but didnt sunff to 2800
