New member, new car with problems - ZR-1 Net Registry Forums

So I'm new to this site, I spent hours reading posts prior to buying my first ZR-1 which is also my first vette. This site has been very helpful to me in making my purchase, and I'm hoping someone out there can help answer some questions about my new ride. Some quick background on the car, 90 ZR-1, 36,700 mi, Borla exh w/ X-pipe, Doug Rippie Motorsports Chip, K&N air intake system, new tires, tinted windows, all else appears to be stock.

Q1- Oil pressure gauge stays pegged out on 80 psi while driving, occassionally dropping to 60-70 psi for couple seconds max, but always jumps back up to 80 psi. Needle does not sweep or flicker or go to 0 psi, stays steady. Is there a by-pass or something not working in the engine or is oil press. sending unit bad or??
Q2- With power key in full power position, the indicator light for it does not illuminate on the information panel. There is no obvious power difference when switching between normal & full power, and switching is done while in parameters rpm wise with owners manual and even shut car off, switched, and restarted. Car runs like a top and smooth through all rpm's, but it feels like it's running on about maybe 250 hp instead of 375 hp. There is an INFL REST light on the control panel lit up and seat belt light on while driving, will either of these or high oil psi lock out the full power function from working correctly. And there is NO Check engine soon light on or any other lights lit on the dash while engine is running, and coolant temp is at operating range as per owners manual.
Q3- When decelerating any speed, any gear. There is a what sounds like perhaps an electric kick down that engages instantly when throttle pedal returns to full upright position, stays on for 1 second, then off for 4 sec, then on for 1 sec and so on until car has slowed down. If you tap brake pedal, the noise stops as well as if push in clutch and down shift to a different gear.
Sorry that was allot of info. Any help on these items would be greatly appreciated. I'm excited to own my first Vette and am enjoying to car so far, but I'm beginning to freak out about if these are gonna be huge ticket items to get fixed. Thanks again
