how much boost

[festerfm]

here's the deal.. got apr stage 1+ done this past friday. and it feels very strong... i got my boost gauge hooked up and got nervous.. first gear doesnt go over 15psi... 2-3 gears go to 20psi... but in 5th gear, when my foot is to the floor, it tends to surge a bit between 22 and 25psi and can spike at 28psi!?!?!? that concerned me since i thought stage 1 was only 18psi or so and 1+ didnt go much higher than that and i was concerned with the surging. is that an n75 issue? could the gauge just be wrong? should i not worry about it? it's a stock motor w/ 97k miles. runs good, no knocking or any odd noises. i imagine its due for timing belt in 8k miles or so. it just makes me nervous running that much boost on stock motor since i dont kno how much it can take especially w/ the boost spike. any info is greatly appreciated!!

Sounds about normal. Do the spikes happen when the motor or the outside temp is cold?

no, its about 65 out and somewhat humid... but i didnt want to keep puttin my foot to the floor if a 28psi spike is going to be armageddon for my engine..
