Hello. I have a 01 L and all my work was done at REM. (look in sig)
I was wondering if it would be worth to have it dyno tuned? About how much HP should i expect?? Thanks

 

A dyno tune is always worth it. With our truck, when Sal was down here in Houston tuneing HALO trucks, we actually lost 10HP but picked up 32Lbs of TQ over the mail-order PSP chip. This should be good for a tenth, if not two; but well see next weekend.

You should easily be in the 400/500 club with those mods and a tuned chip.
