says poston 91. 86-87stk inj should i put factory back in? sorry picout of focus...

Keep it in, as long as the car runs right. There would be no point in putting the original back in. The chip that's in there is a 91 octane chip, where the factory chip would cause detonation using today's 93 octane fuel.

Or you could get an adjustable chip from Eric or Bob.

thanks guys. newbie, so are Eric and Bob from Turbo tweak chips? i will need new injectors(stock) and a chip to match!

Eric (Turbo Tweak) and Bob (Bailey Enginering) both are great and adjustable.

I have experience with Poston's 93 chip and I'm assuming the 91 is similar. There are no radical changes in the 93 chip and I agree with John, its better than the stock chip for stock injectors. If you decide to upgrade the injectors, then get a new chip.

looks like lots of upgrades from years ago, so thanks for the advice...
