Only that if he'* cruising and not beating the heck out of it, that his temps were too high.

no I was'nt beating it, I was just cruising around, but it was alot of stop n go, I noticed the temp mostly stayed around 185 when I was on a main strip, then when I got closer to home on the slower residential roads I noticed it get hotter it seemed like 1 degree every 2 miles by the time I parked it I was sitting at 200, so I sat and let it idle, and the temp still went up before topping of at 204, I'm thinking mabe that aux cooler was too small, its about 1/4 the size of the radiator

oh yeah I thought I'd also post that I finnaly swapped the eproms, dont run any different, an interesting side note about the trans temp too, with the old computer in it before i had the qdm fault it showed the temp reaching 300, and eventually throwing a P0713 code, but it jumped around alot and would skip a whole temp range at times this computer didnt do any of that yet, but I havent drove it around since this morning, so I'll keep ya'll posted on my progress

Will the TCC shudder when going into third? My guess is no, right?

Default chuggle

So far so good. I cured my chuggle. Car now pops out of OD under load.
And all I did was advance the TPS .05.

I've got a spare TPS from a 93 SE. GMPD lists different numbers from my year. Think they'll swap if I can't get a good voltage range out of mine?

you could allways look up the P/N'* for each year and see if they match.

Default IAC

I tried my spare IAC for my C motor and it worked in the K.
The elct. plug was 90 deg off though.
