I am finally Supercharged
Comptech Kit with Aftercooler, 7Psi pulley, Tech2 FMR for A/C and Gozilla BOV. Tuned with Emanage.

few questions
1)After my engine warms up (3 bars) and give it the first run to redline i get slight hiccups (not bogging)just after 6000rpm up to redline.
the strange thing is it only does it on the first run.

2)Peak boost reading is not always constant at redline. the max i saw was 6.9psi and min was around 5.8psi. Is this normal ?

i still need to replace my plugs (currently running IK22). Had to order them from US since i did not find any local NGK 7173.

Thanks

 

My Vortech does something similar (not quite the same). During the first warm up stage, if I'm just running at steady state with very slight changes in rpm, the engine will have a single "hiccup" between 3000 and 4000 rpm. Like you, it only happens after the first cold start of the day and only once. If I accelerate briskly past that rpm and don't let it hang around in that area till after the engine is up to operating temps, I can prevent it from happening at all. I attribute this to the MAP clamp cutting in the first time as the boost becomes significant. Perhaps your Comptech is similar but manifests itself with a slightly different symptom.

Did you solder all your ESM connections? Comptech seems to be very suseptible to crimp connections.

As for your variable boost reading, perhaps you have a slight leak in one of your vacuum/pressure lines. I've seen reports here that having a single dedicated vacuum line (with no "T's" in it) for the FPR will help to produce a more stabile a/f ratio when in boost. Perhaps having fewer "T's" in any given line will also help with a more steady boost reading from your gauge. My boost reading is rock solid and is the same every time at redline.

 

[QUOTE]My Vortech does something similar (not quite the same).

 

You can take vacuum/pressure feed from several places on the intake manifold. that one that Comptech chooses is only one. Any of those rubber hoses going across the manifold can be "T'd" into. However, if you use the PCV line, you should put on a vented catch can first.

I can't help you with your other question.

 

I probably found out why my boost is not always constant at a specific rpm. I did some runs in the afternoon and was getting constant 7.4psi at 9000, late at nigh a was getting 6.6psi. Humidity

 

Whats humidity I haven't seen any since December. Might as well be the desert here.

 

I don't know there but here its currently 93% humid.
