Post the tahoe on the dyno...19hp with just a tune

ok so we drove 250 miles t this guy to tune my cusiens 2008 tahoe

mods are knn intake+filter and deleted cats

the tahoe put down 270.33whp with the speed limiter





after we remover SL we got 273.xx whp

and after tuning the a/f,spark timing,oil presure, etc etc

the hoe put down 289.89 whp


after




the result was 16.53 whp

the tune was done by EFI Live on a DYNO JET dyno

we got 288.xx and then we removed the restrection from the MAS sensor and added almost 1+hp:thumbs:

of corse the tranny shift ponints and evey thing else was tuned

what do you guys think?

It appears the tune did its job. What octane rating was this tuned for?

What's up with the guy in the long white lab coat in the video?

IMO, i would have expected more, I am not talking #'s but the shape of the HP curve... It looks like it flat out falls on its face at 4800??? I would have at least expected it to pull to 5400ish...

Not bad at all. Mine made 286/301 with just intake, muffler and blackbear tune in 90 degree heat. Torque converter unlocked too.

Possibly could have gotten more out of it if it wasn't on an inertia dyno.
