ok so my friend put a p28 in his 94 teggy gsr and we want to know where to get a chip to up the redline and things like that

What mods are done to necessitate the higher redline? I hate to tell you this, but if you really don't know what all is involved in chipping an ecu, you should really leave that up to the professionals. If not done properly, you could mess up the parameters in which the engine runs off of thus damaging your motor.

ok we need it to go to stock red line which around 8000 and it cuts out at 7400 right now cuz its a p28 ecu made for a SOHC

Is the motor stock, why not run the stock ecu? What mods necessitate the use of the P28 ecu - is the ecu even socketed?

i am a weasel has a strong point. what mods do you have? why would you run an unchipped p28 anyways?

pm mtber here on honda-tech he's with phearable.net one of the most reliable chipping/socketing services.
or go on phearable.net yourself; they have all the faq's , prices, videos, anything you want to know about chipping an ecu

x2 phearable is very reliable. John will help decide if/what you need.

Why would you remove your stock ecu for SOHC ecu....comon! You can chip what ever ecu you have...This noobie...But first your car must be modified, not just a rice can exhaust and an ebay header and intake.....hahaha! to funny!
