Trouble at the track :(

[Dreamspawn]

Ok last time i was running consistant 14.3s with my fiance and a extra battary in the car*forgot the battary was in there * Ok so i put on my boost controller and turned it up to 14.5-15psi and went back thinking high to mid 13's but much to my dismay during the first pass when i would hit 5,000rpms after launch it would sound like i was redling 0.o ok tried it again then i backed to boost down to stock 12psi still doing it 0.o

Ok talk to a guy there with a Eclipse GSX 1st gen 16g 650cc Evo injectors he asked if i had stock exhuast i said for now he said it might be backing up and causing pre dotonation??

BUUUUUTTT!!!! i will admit i cheated i didn't vacum cap the one line i crimped the hose zip tied it.... so could this be my problem... Or is it predetonation OR WHAT!!!!????

Probly blow out.

Tune up time.

Also my trouble at the track >>> your "trouble" at the track

I'll take ignition problems over a blown diff anyday

haha, good call stealthee, sorry about your diff dude!

I dont think that your exhaust would cause that, but you could always get a new downpipe and see if that fixes it, they arent that expensive, and you really dont need an aftermarket cat back.

Dude that still sucks ever figure out why this one did it i know the last was suspension etc.. i'm doing a oil change today think i need plugs if so kind?

my car was doing that for awhile and i didnt know why.

i adjusted the gain and the boost and it went away

I havent tore the second one down yet. Maybe the internals will give me some sort of idea.
