I just completed installing a Topgun 160 Chip in my car. I have the epprom programmer and burned the chip myself. The car now sounds angry after the tune but I am experiencing a few issues now.... The HUD now does not work, it reads 0MPH as well now the dash reads 0mph. Check engine light is now on but there is no code to pull? other than these issues the car now seems to run much better. Also the engine has a very light miss like once every 20 seconds only around 1-2000 rpms.

Any advice on the tune?
Also if anyone is interested I can burn Chips for you, just PM
Sounds like the tune aint quite right, sounds like its a 5 speed tune. Not sure about the Speedo thing thou. Looks like you will have dueling needles just like mine..

:laugh: Welcome to tuning. So I'm willing to bet you speedo issues are the VSS constants got hosed up. Do a bin compare and check it out.
How about a log file at idle and a drive. You can't really tell without that......need to see your int and blm and see what you did.
What are your mods? I have plenty of tunes I could let you try send me a pm if you are insterested.
Current mods are:
K&N air filer
ford yellow top injectors
walbro 255 fuel pump
rebuilt transmission
