03 cobra tuning question with diablo sport

[cogdillb]

My 03 cobra has 3" exhaust, off road x pipe, conical filter, diablo sport predator
And just had a 2.81 upper put on. I'm running the 91 pulley tune.
Under wot the car runs awesome till 4500 or so and acts like its blowing spark out. Waiting on custom tune but wanna play a little till then.
Any suggestions on retarding spark or fuel adjustments till then? Waiting on lower and porting before custom tuning.
Thanks

Hope your engine survives the playtime detonation.

I don't need a smartass response just advice.

Don't go WOT till its tuned or at the very least have a good wideband on it... the stock tune is very fat.. i think a 3.1 or so was the smallest pulley you could go with out a tune..

But its not worth it.. put the pin back in

When you running with boost and a supercharged engine you cant short cut this stuff. This isn't bumping the timing up on your 91 5.0 GT. Your gonna melt a piston, man.

I'll just let her sit till mods are done. Thanks for the advice guys.

U need a wide band and go in ur preditor and take 3 or 4 deg of timing out at wot. Or put put some good gas in the car and watch ur af ratio unde wot. Just my 2 cents. Best luck and have fun
