hp loss from no tune
about how much hp and i losing from not tuning my car. i have lots of work inside and out but it idles funny here and there. also i just installed a wet nitrous kit and its obvisouly bad to run it on a untuned engine but will she blow. i'm using small jets.i have a superchip on it but doubt that helps.

RE: hp loss from no tune
The chip could be a bad thing unless it was tuned to work with the nitrous. It changes the spark timing and fuel curves. If your running nitrous you should run some cooler plugs and retard the timing a bit too depending on how mush nitrous you play to run. Tuning is always a good idea after you add something. If its a minor bolt on taking it in for dyno tuning may be overkill, but it couldn't hurt.

so i should remove the chip and battery cable so my computer can restart without the chip and dyno tune it. its pretty expensive though. btw i got the chip before i installed the nos

RE: hp loss from no tune
is it a basic chip ? or custom burned for your car ?
if basic...it just advances timing....so yank it and do it yourself
at MOST....your losing 30 hp, and your not really losing it....your not gaining it by burning a custom chip
5.0 doesn't NEED a tune...it'll do it by itself, but you might tweak another 30 out of it
90% of the time idle/drivability issues are vacuum related
