well, just install a paxton novi2200 on my 08 gt, the car fired up after i load the tune, so i m think of a test drive, then, the engine dead after 200 feet away from my garage... try to load tune to get codes, and then i got 2,

p0355o ignition coli E(cop-e)primary/secondar ck t
p0443 evaporative emission system purge control valve ck t

i was suppose to enjoy the test drive, now its back to fixing..

btw, i m running still running 87 octane gas after the installation, cuz i still has 1/4 left and i want to wait to use all of them then, use the premium fuel..any help would be appreciate..

i have to recommend you drain the 87, just to
risky.

i'm not sure what's going on and why it won't start. check
all electrical connections.

If your problem started after the tune then 99% of time the tune is the problem.

my problem before loading the tune...

raywang5

why risky?

hammeron

risky because the tune you loaded is probably
for 91 octane or higher. even people with
just a cai can get pinging, if they run gas that
has a lower octane than what the tune is
optimized for.

if you must run it with 87, be sure to keep the
engine load very light.
