To Tune or not to Tune...

[miclightning]

Hey guys... been a while.

I got another Lightning, its got a built motor, built trans, 4.10's and a Detroit locker.

Currently I haven't even touched the motor since break in, so its got a stock tune, stock pullies..

long story short is def running rich, all i smell is fuel out of the pipes, and i am getting SH!T gas mileage.

Here is the question, would it be worth it to throw a 6lb lower, dif upper, and an EMAIL tune? Only reason I am not trying to drop $500 for dyno tune is the truck is for sale, but I would like to see what it could do with dif pullies.

here is a complete list of mods:

New 5.4 block
Manley rods
Manley pistons
Forged crank
ARP head studs
ARP head bolts
PI heads
PI cams
Electric Fan
MMR oil pump
JDM intake

Kooks LT's
Gutted Cats
Dynatech catback

built trans
PI 2400 stall trq converter
valve body


4.10's
Detroit tru trac

Thanks all

- Sean

I say if you're going to do it you should do it right. I'd get a tune on it even if it's only an email tune.

Leave the pulley off and get a email tune to address the rich issue and let the new owner do it his way.
