Picked up more in the HP than torque still good gains in both.I cant figure out how to put the to RPM AND TRQ Graphs on here any sugestions?But anyway this dyno was done today at the local engine shop it was not at the rear wheels.Still cost me 40 bucks I didn’t have lol.I also found out the previous owner installed the HO cams already.Why I do not now must not of been a lease guess gas just got to high for him.SO this is with the Superchips on performance setting,Bissine Ys and Cat, Gibson shortys and swept side,K&N CA and the HO cams 93 Octain gas. (3:92 Gears stock I guess)Let me know how to copy the graphs on here I have a scanner.It starts dropping of after 5500rpms I guess the peak Hp is 283 Peak torque 326 Im happy.Now I got to find a Strip to see my 1/4 mile times the Quad Cab will probably Kill me.(weight)

i've seen STS (remote turbo's)
in person twice and on TV
i gotta say i love them!
wish they had them for the older daks
i mean they are alot easier to install
& no intercooler needed
(heat and over heating the turbo/over heating the incoming air issue's are gone)
cant remember exactly the last show i seen one installed in
guys the Dyno numbers done b4 and after kicked azz
these things are sweet!
don't know if their all the same the one's i seen took the place of the muffler
(STS installed & no muffler at all)
and the sound out back was right on 2
