"hi guys, ive got a 97 12 valve with #100 fuel plate, 4" exhaust, 16.5 timing, boost elbow, southbend dual disk, and complete guages. the truck makes good power and about 38 psi boost under full throttle. i would like to lower the smoke level under low boost conditions. would a afc spring kit help quite a bit? also i am looking at
the 3k spring kit to free up a few more rpms. any negative driving charastics with them? also with your experience what would be a good injector/ turbo combo to make 500 drivable horsepower. thats my ultimate goal. thanks
correct if remember correctly toward the motor gives u more fuel.. i would slide the afc back a little.. it cleared up the exhaust on mine for my e-check.. i have a 100plate also, slid the afc back all the way and the plate slightly and i passed!!!! thank god the guy thought my muffler was a cat conveter!!!
yes. the plate is at full forward. the exhaust cleans up when boost pressure comes on.
ive been thinking of doing an injector upgrade. should i put in a less agressive fuel plate with a larger injector? was thinking a 75 horsepower dd injector. i know im going to need a turbo upgrade. the truck has 294,000 miles and im sure the factory injectors arn't quite up to par.
