Re: 92 Typhoon chip

So if I wanted to take the Ty to get dyno tuned I would need the 3 bar? Then they can make all the adjustments through it correct?
The 3bar map enables the ecu to see more then 14.5lbs of boost.. if you up the boost with a 2bar chip and map.. the ecu will only see at max that 14.5lbs and supply enough fueling even if your at 20 plus you'll only get fueling to fill the 14.5lb need which is why everyone suggest going with a 3bar map, and a chip calibrated for the 3bar map before bumping up the boost at all. There's a good explanation of it on
www.sytychips.com I believe.
Also you can't make adjustments thru the map sensor, you have to actually edit the bin file on the chip. Again read in the tuning section.

How much can you up the boost with out needing new injectors to compensate? To step up the fuel system what all is required? Just a intank pump, injectors, AFPR and a fuel gauge?
Stock injectors have gone 11's I think but that's with meth.. It's different for each truck i've seen.
Check out the tuning section.. in order to tune there's more to it then just adjusting the fuel pressure but yes afpr and fuel pump are must but I wouldn't do anything until you replace your stock fuel pump with the walbro 255.. The stock fuel pump is barely enough for a stock truck since it was originally used on n/a trucks lol.
Also get the truck running 100% first before you go upping the boost or dyno tuning it for the most out of it.. These motors have week internals and don't handle kr well so I would suggest before you start digging into performance, do allot of reading on here and locate a syty owner who is local to you that has datamaster or some other type of data logging program that they can hook up to your truck to ensure it's running good enough to screw with.
