tried 780 primaries same bog but that was before i installed wideband so i dont know if it was lean or rich . I checked my tps last night at tps and on three pin connector top pin that is alone (green+red) showed like 1.69 at closed postiton which meant out of tune , but it went to 4.85 full open . Checked black wire on bottom it showed like .04v closed and same open which leads me to belive that my tps is bad . last wire showed 4.95v at all times so i figured that was the power feed for the tps ,IDK i couldnt really find a clear thread for s4 tps adlustment so that is the DL so far

where are the most common places for vac leeks , i dont have but two vac lines and i know all boost hoses are not leaking bc i checked them time after time and used t bolt clamps so that pretty much leaves block off plates some of which dont even have pressure and uim and lim right ? ooh and definately not a vac leak b/c at 3000 rpm's at full throttle i have built up 5.5 psi and sill lagging like a snail and as soon as secs kick in bam wheel spinning power all the way to redline. the car is also really hard to start after getting warm and not letting cool down before trying to crank again.i havent checked compression yet . Car allways cranks when cool but i have to hold throttle to floor as if i have a leaking injector or something. but i do think tps is bad though so next ill try and find a good or new one soon
