I've noticed that my car has been having trouble red lineing for some reason. I don't know if it has to do with the spark plug gap, ignition wires, fuel pump, fuel pressure or timing. Any advise will be greatly appreciated.

I have my plugs gaped at .44
I have my timing set at 13*
I am running stock ignition w/MSD cap and Accel 7mm yellow wires
stock fuel pump
and fuel pressure hasn't been checked to see if its set at correct setting.

What are your mods and in what gear are you trying this? i went pretty close to redine if i did not hit it, i was not trying to there's power loss up there depending on what you are doing.

Usually, the #1 culprit behind "having trouble redlining" is the coil. It can't keep up with demand and hits a brick wall, so to speak.

Typhoon upper and lower (ported), CAI, 24# injectors w/c&l 76 mm MAF, shorty headers, adjuster fp, 1.7 cran cam rockers, 3:73 rear-end, full H-pipe 2.5in flowmaster dumps, 70mm TB, 5 speed. and its doing this in first gear. it redlines at 6,000 but it has trouble getting to about 5,200rpms. it will hesitate for a second or 2 at about 4,900 rpms and then it will redline.

Stock heads? What's the afr at that rpm?

I say again. Coil.

stock heads. i will swap out the coil and give that a try.

I would think fuel filter too. If they get clogged pretty bad, it won't redline. Take out a plug and see if they are white.
